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 transgressor, punish a convicted transgressor, or intimidate people. 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.[1] Instances of lynchings and similar mob violence can be found in all societies.
