On FB where I saw and stole, one of the friends of the friends I stole this from mentioned a news story from a couple years ago where apparently a 40 year Gurkha vet had just gotten out and was on his train home when a band of 40+ thieves stopped the train, boarded, and started pillaging. When they got back to the guy's car they decided to gang rape a teenage girl in there. He decided that was enough.
After killing 11 of them by himself, they finally ran off. He only had a cut on his hand.
