The basic components of an offense are listed below;
generally, each element of an offense falls into one or another of these categories. At common law, conduct could not be considered criminal unless a defendant possessed some level of intentioneither purpose, knowledge, or recklessnesswith regard to both the nature of his alleged conduct and the existence of the factual circumstances under which the law considered that conduct criminal. However, for some
legislatively enacted crimes, the most notable example being
statutory rape
In common law jurisdictions, statutory rape is nonforcible sexual activity in which one of the individuals is below the age of consent (the age required to legally consent to the behavior). Although it usually refers to adults engaging in sexual ...

age of the accuser) that rendered his conduct criminal; such crimes are known as
strict liability offenses.

Mental state (''Mens rea'')
'' Mens rea'' refers to the crime's mental elements of the defendant's intent
Intentions are mental states in which the agent commits themselves to a course of action. Having the plan to visit the zoo tomorrow is an example of an intention. The action plan is the ''content'' of the intention while the commitment is the ''a ...
. This is a necessary element—that is, the criminal act must be voluntary or purposeful. ''Mens rea'' is the mental intention (mental fault), or the defendant's state of mind at the time of the offense, sometimes called the ''guilty mind''. It stems from the ancient maxim of obscure origin, "actus reus non facit reum nisi mens sit reas" that is translated as "the act is not guilty unless the mind is guilty." For example, the ''mens rea'' of aggravated battery
Battery is a criminal offense involving unlawful physical contact, distinct from assault which is the act of creating apprehension of such contact.
Battery is a specific common law offense, although the term is used more generally to refer to ...
is the intention to do serious bodily harm. ''Mens rea'' is almost always a necessary component in order to prove that a criminal act has been committed.
''Mens rea'' varies depending on the offense. For murder, the mental element requires the defendant acted with "malice aforethought
Malice aforethought is the "premeditation" or "predetermination" (with malice) required as an element of some crimes in some jurisdictions and a unique element for first-degree or aggravated murder in a few. Insofar as the term is still in use, ...
". Others may require proof the act was committed with such mental elements such as "knowingly" or " willfulness" or " recklessness". Arson requires an intent to commit a forbidden act, while others such as murder require an intent to produce a forbidden result. Motive

has reduced mental states to four. In general, guilt can be attributed to an individual who acts "purposely," "knowingly," "recklessly," or "negligently." Together or in combination, these four attributes seem basically effective in dealing with most of the common ''mens rea'' issues.
Conduct (''Actus reus'')
All crimes require '' actus reus''. That is, a criminal act
In ordinary language, a crime is an unlawful act punishable by a state or other authority. The term ''crime'' does not, in modern criminal law, have any simple and universally accepted definition,Farmer, Lindsay: "Crime, definitions of", in Ca ...
or an unlawful omission of an act, must have occurred. A person cannot be punished for thinking criminal thoughts. This element is based on the problem of standards of proof. How can another person's thoughts be determined and how can criminal thoughts be differentiated from idle thoughts? Further, the law's purview is not to punish criminal ideas but to punish those who act upon those ideas voluntarily.
Unlike thoughts, words can be considered acts in criminal law. For example, threats, perjury
Perjury (also known as foreswearing) is the intentional act of swearing a false oath or falsifying an affirmation to tell the truth, whether spoken or in writing, concerning matters material to an official proceeding."Perjury The act or an inst ...

are offenses in which words can constitute the element of ''actus reus''.
The omission of an act can also constitute the basis for criminal liability.
Concurrence
In general, ''mens rea'' and ''actus reus'' must occur at the same time—that is, the criminal intent must precede or coexist with the criminal act, or in some way activate the act. The necessary ''mens rea'' may not continually be present until the forbidden act is committed, as long as it activated the conduct that produced the criminal act. However, for criminal liability to occur, there must be either overt or voluntary action.
Causation
Many crimes include an element that actual harm must occur—in other words, causation must be proved. For example, homicide requires killing, and aggravated battery requires serious bodily injury and without those respective outcomes, those respective crimes would not be committed. A causal relationship between conduct and result is demonstrated if the act would not have happened without the direct participation of the offender.[
Causation is complex to prove. The act may be a "necessary but not sufficient" cause of criminal harm. Intervening events may have occurred between the act and the result. Therefore, the cause of the act and the forbidden result must be "proximate", or near in time.][
