> Lynching is an extrajudicial punishment by an informal group. It is most often used to characterize informal public executions by a mob in order to punish an alleged transgressor, or to intimidate a minority group. It is an extreme form of informal group social control such as charivari, skimmington, riding the rail, and tarring and feathering, but with a drift toward the public spectacle.
Yes it does happen with frequency in some places, yet it is a terrible reminder of how savage we humans can be to one another.
