I can understand people's frustration, but I would point out that the vigilante groups in the US back in the 19th Century existed only until such time as courts and law enforcement became organized and effective. I'm not talking about lynchings in the South, but vigilantism is the West, especially in the mines of Idaho and Montana.

Often a low-level crook was given warning and then banished. Trial were actually held and some of the accused were acquited.

But why were the RCMP and the provincial police sitting on their hands?
