I dont know of any real vigilante examples on Police in US.
https://en.wikipedia.org/wiki/Christopher_Dorner_shootings_a... Christopher Dorner is one example. He was fired for reporting a training officer for police brutality and then decided to start killing police and their families. It was an utter shit show. > At about 5:30 am (PST), at least seven LAPD officers on a protection detail of an unnamed LAPD official's residence in the 19500 block of Redbeam Street in Torrance…
Wow, shit show indeed. If Im reading this right Dorner failed to kill even a single dirty/bad cop he was accusing of using excessive force. He killed "daughter of Randal Quan, the former LAPD captain who represented Dorner at his 2008 dismissal hearing" and two random police officers. Looks like revenge, not vigilantism.
