Responsibility for criminal law and criminal justice in the United States is shared between the states and the federal government.

Sources of law
The federal government and all the states rely on the following.
Common law
Common law is law developed by judges through legal opinions, as opposed to statutes adopted through the legislative process or regulations issued by the executive branch. A common law crime is thus a crime which was originally defined by judges.
Common law crimes no longer exist at the federal level, because of the U.S. Supreme Court's decision in United States v. Hudson and Goodwin, 11 U.S. 32 (1812). The validity of common law crimes varies at the state level. Although most states have abolished common law crimes, some have enacted "reception" statutes recognizing common law crimes when no similar statutory crime exists.
Statutes
All 50 states have their own penal codes. Therefore, for any particular crime somewhere, it would be necessary to look it up in that jurisdiction. However, statutes derive from the common law. For example, if a state's murder statute does not define "human being," that state's courts will rely on the common-law definition.
State vs. federal
The states, since they possess the police power, have the most general power to pass criminal laws in the United States. The federal government, since it can only exercise those powers granted to it by the Constitution, can only pass criminal laws which are related to the powers granted to Congress. For example, drug crimes, which comprise a large percentage of federal criminal cases, are subject to federal control because drugs are a commodity for which there is an interstate market, thus making controlled substances subject to regulation by Congress in the Controlled Substances Act which was passed under the authority of the Commerce Clause. Gonzales v. Raich affirmed Congress's power to regulate drug possession under the Controlled Substances Act under the powers granted to it by the Commerce Clause.
Model Penal Code
The Model Penal Code ("MPC") was created by the American Law Institute ("ALI") in 1962. In other areas of law, the ALI created Restatements of Law, usually referred to just as Restatements. For example, there is a Restatement of Contracts and a Restatement of Torts. The MPC is their equivalent for criminal law.
Many states have wholly or largely adopted the MPC. Others have implemented it in part, and still others have not adopted any portion of it. However, even in jurisdictions where it has not been adopted, the MPC is often cited as persuasive authority in the same way that Restatements are in other areas of law.

Theories of punishment
Principle of legality
An overarching concept in American criminal law is that people may not be punished for committing merely immoral or unethical acts. They can only be punished if that act has been announced beforehand as a crime.
Burden of proof
In the United States, the adversarial system is used. The prosecution must prove each element of the alleged crime beyond a reasonable doubt for conviction.
Elements
Crimes can generally be reduced to actus reus elements and mens rea elements. Actus reus elements are elements which describe conduct. Mens rea elements are elements which identify a particular mental state.
Actus reus
The phrase "actus reus" is typically translated as "guilty act."
Voluntary act
Ordinarily, a voluntary act refers to commission. However, as discussed below, some crimes do punish failure to act. A status is not a voluntary act. For example, no law will be constitutional that makes it a crime to be addicted to illegal drugs, as opposed to using them, as happened in Robinson v. California.
Omission
Failure to do something can occasionally be criminal. For example, not paying one's taxes is criminal. Typically, the criminality of failing to act will be codified.
Status relationships
Certain relationships create a duty to act at common law, such as spouse to spouse, parent to child, or employer to employee, for example.
Contractual duty
A person may contract to act, such as a babysitter to render aid in the event of the child in her care hurting himself.
Creation of risk
A person typically has a duty to act when he is responsible for putting the other in peril in the first place, such as through accidental injury.
Creation of reliance
A person may have a duty to act when he begins to act but then stops. This situation typically arises in the hypothetical where a person is drowning. One bystander among many starts swimming out to rescue him but simply changes his mind halfway and decides to turn around and go back to shore alone. The rationale for holding the bystander culpable is that the other bystanders did nothing because of his act. If the bystander had been the only person around, he would not be causing others not to assist, so he would not be culpable.
Social harm
Criminal law is distinguishable from tort law or contract law, for example, in that society as a whole is theoretically damaged. Obviously, there are particular victims, but society as a whole is the party responsible for the case against and, in the event of a conviction, punishment of the criminal. Social harm is that part of the crime that is sought to be avoided.
Mens rea
The phrase mens rea is typically translated as "guilty mind" and focuses on the mental state of the accused.
General intent is an awareness of factors constituting the crime; including attendant circumstances. The person must be aware that he is acting in a proscibed way and be aware of a high likelihood that attendant circumstances will occur. The requisite intent may be inferred from the doing of the act.
A specific intent crime requires the doing of an act coupled with specific intent or objective. Specific intent cannot be inferred from the doing of the act. The major specific intent crimes are: conspiracy (intent to have crime completed), attempt (intent to complete a crime - whether specific or not, but falling short in completing the crime), solicitation (intent to have another person commit a crime), embezzlement (intent to defraud), first degree premeditated murder (premeditation), false pretenses (intent to defraud), forgery (intent to defraud), larceny & robbery (intent to permanently deprive other of interest in property taken), assault (intent to commit battery) and burglary (intent to commit felony in dwelling).
A strict liability crime, however, does not require that a mens rea be found.
The MPC also addresses intent. One of its major innovations is the use of standardized mens rea terms (in MPC terms, culpability) to determine levels of mental states, just as homicide is considered more severe if done intentionally rather than accidentally. These terms are (in descending order) "purposely", "knowingly," "recklessly", "negligently", and "strict liability". Each material element of every crime has an associated culpability state that the prosecution must prove beyond a reasonable doubt.
Causation
Actual cause
Actual cause (also called "cause-in-fact") holds that the defendant cannot be criminally liable unless it can be shown that he was the cause-in-fact of the prohibited result. In order to find a defendant guilty, a court must be able to affirmatively answer the question, "But for the defendant's conduct, would the prohibited result have occurred when it did?"
There are some exceptions to the but-for test, however. For example, in a case where multiple wrongdoers "overdetermine" the harm that a victim would have experienced.
Proximate cause
The requirement of proximate cause (also called "legal" cause) restricts criminal liability to those cases where the harmful result which ensued was a foreseeable result of defendant's conduct. It is often phrased that the harmful result must be the "natural or probable" consequence of defendant's conduct.
Concurrence of actus reus and mens rea
Concurrence means the mens rea (mental state or guilty mind) coincides with the actus reus elements. X hates Y and knows that she plays soccer every July 4 at a certain park. July 4, 2010, X goes on a high hill overlooking the field that Y is playing on, and then intentionally dislodges a large boulder, and directs it towards Y intending to kill her. If it kills her, concurrence is complete. Same situation, only the boulder rolls halfway down the hill, then gets lodged on a tree. X does everything he can to dislodge the boulder, but cannot do so. He gives up. July 4, 2011, the boulder becomes dislodged in a storm (or otherwise becomes dislodged in any way other than X dislodging it with the intention of killing Y). The boulder kills Y, just as X intended one year ago. There is no concurrence, and X committed no crime.
Affirmative defenses
There are two categories of affirmative defenses: justification and excuse. Justifications differ from excuses in that a successful justification will show the defendant's conduct was not wrong, whereas a successful excuse does not show the defendant's conduct was wrong. A successful excuse shows that, while the defendant's conduct was regrettable, this particular defendant will not be subject to punishment.
Justification
Justification defenses are full defenses. Society essentially tells the actor that he did nothing wrong under the circumstances.
Self-defense
An accused will typically raise this defense when he is defending a crime of battery or homicide. Under common law, a person may use non-deadly force to defend himself from a non-deadly attack under certain circumstances. For one, he may not be the aggressor. Moreover, he must believe his force is necessary. Furthermore, that belief must be reasonable. In addition, the person must be facing imminent and unlawful force. Notably, the force the person uses need not be actually necessary. It need only appear so to a reasonable person. Under common law, a person may use deadly force to defend himself from a deadly attack under the same circumstances as for a non-deadly attack except that a person may not use deadly force if non-deadly force would suffice.
Other justifications
Other justifications include defense of others, defense of property, law enforcement, and necessity.
Defense of others
Defense of property
Necessity
Excuse
Excuse defenses are also full defenses. However, society is not saying the actor did nothing wrong, only that it will not punish him under the circumstances. Intoxication can serve as a defense, with the law distinguishing between how voluntary and involuntary intoxication can serve as defenses. Mistake is another defense and can be a mistake of fact or a mistake of law. Other excuses include duress and insanity.

Crimes
Homicide
Only a human being can commit a homicide (as opposed to other legal persons, such as corporations). He does so when unlawfully he kills another human being. The two categories of homicide are murder and manslaughter.
A person who accidentally causes a fatal car accident because they lost control on black ice and killed a child is still considered to have committed "homicide," but is not punishable as long as it is proven that it was a truly, tragic accidental car wreck. While homicide is a word carrying a criminal connotation to the layperson, from a legal standpoint it is merely the "unlawful killing of another human being" and may not be punishable.
Murder
A human being commits murder when he commits a homicide with malice aforethought, an "endangering state of mind." There are four ways to satisfy the element of malice. One is an intent to kill and is the only form of express malice. The remaining ways are implied malice. One is an intent to inflict great bodily harm. A third is a reckless disregard for the value of human life, sometimes called depraved heart. The last only applies when someone dies during the commission or attempted commission of a felony. It is often called the felony murder rule and only requires the person to intend to commit the underlying felony.
Degrees of murder did not exist under common law. Most states have statutorily created at least two degrees of murder. Usually, a person only commits first-degree murder when he has express malice. If he has any other type of malice, he usually commits second-degree murder. American law reformed old world, common law practices during the ages of Henry VIII where even petty thieves were executed. American law generally categorizes the level of punishment and created lesser sentences, as opposed to the common law "one size fits all," hence the first, second, third and fourth degree murder with different level of punishment. (See voluntary manslaughter)
First-degree murder
First degree murder is proven when malice aforethought accompanies "willful, deliberate and premediation" of the criminal homicide. Since it is the harshest degree of murder in terms of sentencing and societal punishment, a first degree murder must be especially premediated. Premeditation is the time and capacity to appreciate the enormity of the evil imposed. It involves weighing the pros and cons of one's own actions, and allowing one to think calmly, rationally and thoughtfully. A planned event, with a design to maliciously murder another human being, such as a gang member planning a contract murder or a serial killer outlining the steps to kidnapping his next victim, are committing premeditated acts when, if caught and charged, usually are proven to have committed murder in the first degree.
Second-degree murder
Second degree murder, however, initiated by any other crime which satisfies the general malice aforethought whereas "malice is merely implied."
The MPC does not categorize murder by degrees.
Voluntary manslaughter
Voluntary manslaughter is the lesser charge of homicide, lesser than murder, for a reason that has come down by American law taken from the felony murder rule doctrine of the common law. American society has come to understand how a loss of self-control, brought about through emotional states, can push a person toward murder when it is not rationally intended. Since Henry the Eighth, common law practices were harsh whereas petty thieves were executed, as well as criminals whose motives were understood as emotionally challenging to maintain self-control. Voluntary manslaughter, although punishable, is an intentional, malicious form of homicide that involves certain elements to justify this lesser charge.
The "Heat of Passion" and "Cooling off Period" are subjective justifications that are argued in court, by attorneys, based on circumstantial evidence and establishment of motives where proof of a crime may not be fully ascertained. The ideas that a person, whom upon walking into his bedroom, observes his wife having sex with another male (his lifelong rival), reacts harshly, grabs a nearby gun, and within a matter of minutes, kills both of them, is less punishable than other forms of deliberate, premeditated and willful acts of calculated murder. A person is still "hot," the heat of passion is so great that reason is dismissed and primal aggression takes over, but it was never the natural intention of the person ever--with no evidence of ever having marital problems or the like. Because he or she walked in on his partner's infidelity and kills both of them within minutes, he or she has no chance to cool off. However, the heat of passion and cooling are subjective factors.
According to the law, a murder charge can become a voluntary manslaughter charge if there is proof of "legally adequate provocation," the objective test. This truly objective standard combines heat of passion and cooling off to determine them from the facts of a case. The question is, "Does the defendant have legally adequate provocation to have lost control?" In situations of infidelity described above, he does, according to America's general interpretation. (Facts of a particular case may override some of that matter, however). Insulting words alone cannot justify legally adequate provocation.
Think about reasonably adequate provocation in terms of a stressful trigger to a loss of self-control. The law says insulting words, or words alone, cannot justify a trigger of criminal homicide. Your lover cannot call you a name, thereby making you justified in killing them. The legally adequate provocation must go beyond insulting words to events, situations and circumstances that surprise the defendant and trigger them to lose any sort of reasonableness without time to think through the consequences nor weigh the pros and cons. In this way, a court may establish a defendant, originally charged with second degree murder, to have been legally adequately provoked to commit the unlawful act of killing of another human being making his crime less punishable, but still punishable.
Voluntary manslaughter results in a lesser charge than murder, but more than involuntary manslaughter.
Involuntary manslaughter
Although Involuntary manslaughter is unintentional, the law requires proof beyond a reasonable doubt of some form of malfeasance or misfeasance. Malfeasance is considered to be any dangerous, unlawful act (felony), misfeasance includes any act, even lawful, that is criminally negligent (misdemeanor).
Rape
American rape law has transitioned common law practices which grew out of a male centric legal interpretation to the feministic view it has today. A woman once had to prove absolute resistance against her aggressor, and rape reformation laws in America did away with the Hale Warning, corrorborating evidence, and the early outcry doctrine and instead focused rape law reform onto the aggressive, coercive nature of the "rapist." Marital rape law once required "forcible, unlawful and carnal knowledge," and common law once believed husbands cannot rape their wives, so these incidents, if reported at all, were never charged. Women in America have reported more rape with these times, however, only 12% of rapes are currently reported nationally out of the thousands of offenses that occur.
Theft
Larceny
Robbery
Robbery at common law was the trespassory taking of the property of another with the intent to permanently deprive the person of that property by means of force or fear.
Robbery charges result in substantial sentences which may be up to ten years with parole. Robbery with a deadly weapon increases this sentence and depends on the present ability of the defendant during the commission of the res gestae, or "the thing that happened". The precise language of this charge must be carefully reasoned to a jury panel by a trial court judge. In order for a taking to be "felonious", proof must exist beyond the defendant's animus firandi, or "evil in the heart". In other words, robbery is a charge reliant on the notion of possession of property of another and the force or fear used to accomplish the transfer of possession. According to the legal standard, a sleeping man cannot be aware that his property is being stolen. Therefore, a thief cannot be charged with robbery based on the force or fear prior to the incident requirement.
The transfer of property cannot be a voluntary transaction. In looking at property holding, three major distinctions are made in cases where a charge of robbery is not inexplicably obvious. "Mere custody," entitlement, and possession are the three levels of property holding and are specifically important to the precise language of the legal interpretation of what constitutes a robbery. If a person has mere custody of an object belonging to another, he or she is borrowing the object in question. If a citizen loans his vehicle to an associate to go to the grocery store, the associate must return the vehicle. If one purchases a new CD, the purchaser is entitled to the property because it becomes your own under your ownership.
Possession, however, is acquiring an object of another without being entitled to it or allowed to possess it. A person charged with a robbery may have reasonably believed he or she owned the iPod, although they may have been incorrect. Possession, in terms of the legal interpretation of robbery, is 9/10 of the law. Possession, to charge robbery, must be a transfer of property acquired through force or fear. That is, a defendant must create fear through force in order to achieve the possession of the object or property in question, otherwise they may have committed another crime. A person who threatens another with future violence cannot be charged with robbery, because they did not use "force or fear", and insulting words alone cannot allow somebody to be entitled to self-defense. Therefore, a person who holds up victim with a deadly weapon, with or without present ability (bullets in the weapon that is charged and fails to meet its target-assault), and takes possession of a book the victim is holding, is committing robbery according to the law.
The force or fear established by the defendant must precede the transfer of possession of the object in question. This can be said, also, as the transfer of possession must be acquired through the use of force or fear as the tool of attaining such goods in order to achieve all aspects of the legal doctrine imposed, "the felonious taking."
