Crime denotes an unlawful act punishable by a state.The most popular view is that crime is a category created by law; in other words, something is a crime if declared as such by the relevant and applicable law.One proposed definition is that a crime or offence is an act harmful not only to some individual or individuals but also to a community, society or the state. Such acts are forbidden and punishable by law.
The notion that acts such as murder, rape and theft are to be prohibited exists worldwide. What precisely is a criminal offence is defined by criminal law of each country. While many have a catalogue of crimes called the criminal code, in some common law countries no such comprehensive statute exists.
Usually, to be classified as a crime, the “act of doing something criminal” must – with certain exceptions – be accompanied by the “intention to do something criminal”.
