vigilante(redirected from Viglante)
Also found in: Dictionary, Thesaurus.
n. someone who takes the law into his/her own hands by trying and/or punishing another person without any legal authority. In the 1800s groups of vigilantes dispensed "frontier justice" by holding trials of accused horse-thieves, rustlers and shooters, and then promptly hanging the accused if "convicted." A mother who shoots the alleged molester of her child is a vigilante.
