Colorado's last known lynching took place in Pueblo on Saturday, September 13, 1919. Two thugs shot a police officer. Mob showed up at city jail and hung them from 14th Street bridge. I bet criminal activity dropped after that.
There is an account down around South Park around the 1880's of ranchers getting fed up with a crooked judge and they dealt with him.
