OBJECTIVES OF CRIMINAL LAW

Criminal law is distinctive for the uniquely serious potential consequences or sanctions for failure to abide by its rules. Every crime is composed of criminal elements. Capital punishment may be imposed in some jurisdictions for the most serious crimes. Physical or corporal punishment may be imposed such as whipping or caning, although these punishments are prohibited in much of the world. Individuals may be incarcerated in prison or jail in a variety of conditions depending on the jurisdiction. Confinement may be solitary. Length of incarceration may vary from a day to life. Government supervision may be imposed, including house arrest, and convicts may be required to conform to particularized guidelines as part of a parole or probation regimen. Fines also may be imposed, seizing money or property from a person convicted of a crime.

SELECTED CRIMINAL LAWS

1. Elements
The criminal law generally prohibits undesirable acts. Thus, proof of a crime requires proof of some act. Scholars label this the requirement of an actus reus or guilty act. Some crimes particularly modern regulatory offenses require no more, and they are known as strict liability offenses. Nevertheless, because of the potentially severe consequences of criminal conviction, judges at common law also sought proof of an intent to do some bad thing, the mens rea or guilty mind. As to crimes of which both actus reus and mens rea are requirements, judges have concluded that the elements must be present at precisely the same moment and it is not enough that they occurred sequentially at different times.

2. Strict liability
Strict liability is a concept normally applied to civil, not criminal law. It can be described as liability for harm caused by the defendant, regardless of mens rea or intent. Not all crimes require specific intent, and the threshold of culpability required may be reduced. For example, it might be sufficient to show that a defendant acted negligently, rather than intentionally or recklessly. In offenses of absolute liability, other than the prohibited act, it may not be necessary to show the act was intentional. Generally, crimes must include an intentional act, and "intent" is an element that must be proved in order to find a crime occurred. The idea of a "strict liability crime" is an oxymoron. The few exceptions are not truly crimes at all - but are administrative regulations and civil penalites are created by statute, such as crimes against the traffic or highway code.

3. Fatal offenses
A murder, defined broadly, is an unlawful killing. Unlawful killing is probably the act most frequently targeted by the criminal law. In many jurisdictions, the crime of murder is divided into various gradations of severity, e.g., murder in the first degree, based on intent. Malice is a required element of murder. Manslaughter is a lesser variety of killing committed in the absence of malice, brought about by reasonable provocation, or diminished capacity. Involuntary manslaughter, where it is recognized, is a killing that lacks all but the most attenuated guilty intent, recklessness.

4. Personal offenses
Many criminal codes protect the physical integrity of the body. The crime of battery is traditionally understood as an unlawful touching, although this does not include everyday knocks and jolts to which people silently consent as the result of presence in a crowd. Creating a fear of imminent battery is an assault, and also may give rise to criminal liability. Non-consensual intercourse, or rape, is a particularly egregious form of battery.

5. Property offenses
Property often is protected by the criminal law. Trespassing is unlawful entry onto the real property of another. Many criminal codes provide penalties for conversion, embezzlement, theft, all of which involve deprivations of the value of the property. Robbery is a theft by force. Fraud in the UK is a breach of the Fraud Act 2006 by false representation, by failure to disclose information or by abuse of position.

6. Participatory offenses
Some criminal codes criminalize association with a criminal venture or involvement in criminality that does not actually come to fruition. Some examples are aiding, abetting, conspiracy, and attempt. However, in Scotland, the English concept of Aiding and Abetting is known as Art and Part Liability.
