Crimes are generally categorized into felonies and misdemeanors. Felonies are serious offenses such as murder, rape, and burglary, typically punishable by imprisonment for more than one year. Misdemeanors are less severe offenses, like petty theft and minor assault, usually punishable by fines or imprisonment for less than one year.
