Crimes include both felonies (more serious offenses – like murder or rape) and misdemeanors (less serious offenses – like petty theft or jaywalking). Felonies are usually crimes punishable by imprisonment of a year or more, while misdemeanors are crimes punishable by less than a year. However, no act is a crime it has not been previously established as such either by statute or common law. Recently, that list of Federal crimes dealing with activities extending beyond state boundaries or having special impact on federal operations, has grown.
