Dude. I'd have been out of there as soon as he landed the no-hp song and Kostyan showed up. Given Kornuel's edge, he was probably in no danger of dying, so there's not a lot to be gained by staying.
Sucks that they took all your stuff. Whenever I'm involved in a gang that nasty, it makes me want to leave all the guy's gear since it was such a cheesy takedown.
