Lazy writing to solve Ray's problems
So the brilliant idea is just to have Ray and the gang shoot the Russians.
There's 2 problems with this plan.
1. The cops had no reason to let Ray off the hook. It's like, OK, instead of doing a legal bust, you just went ahead and killed them all. It's all good. You're off the hook, and won't go to jail for any of it.
2. The Russians back home could send some guys to the US to go after Ray for taking their guys out. Unless four or five guys was the entire Russian mob, and they all got wiped out while visiting California.
