Racial Profiling and Vigilantism

Vigilantism consists of self-appointed citizens taking the law into their own hands by "arresting," convicting, and punishing an accused person.

Racial profiling is the use of a person's race or ethnicity by law enforcement or security officials as a factor in deciding whether to investigate that person or engage in enforcement (search someone at an airport security checkpoint, make a traffic stop or arrest, etc).

By defintion, racial profiling is a form of racism; not so with vigilantism. Vigilantes typically attempt to conceal their identity, hence the masks and robes used by the Ku Klux Klan.
