There was this Vietnamese club which was quite popular/ we're going back 20 yrs

Word was, the owner used to pay off the local sergeant or someone high up- on the condition that fights do not break out in the streets- causing a disturbance

That way, the local cops would turn a blind eye to all the trouble which was plentiful for that club. Eventually they had one too many murders and it lost its license

I've heard first hand accounts that when trouble was going to flare, the owner would literally lock the doors and let the two parties fight or kill each other

So unfortunetly for the losing party it was a death trap
