Lynching is an extrajudicial killing by a group. It is most often used to characterize informal public executions by a mob in order to punish an alleged or convicted transgressor or to intimidate others. It can also be an extreme form of informal group social control, and it is often conducted with the display of a public spectacle (often in the form of a hanging) for maximum intimidation. Instances of lynchings and similar mob violence can be found in all societies.
