I'd give it all to a homeless person, while leaving plenty of clues for the heavies to track him down. I'd watch the fun unfold from a safe distance and then write it up as a movie script. Make a fortune from the movie. Probably get Tony Scott to direct.
I'd assume that Vic Mackey was trying to fit me up for the Armenian Money Train Heist and wouldn't touch it with a bargepole.
I think I've got one of those personalities that would let me down. I'd spend so much time looking over my shoulder, out the windows through drawn curtains and the like, that I'd begin to wonder if it was all worth it. I'd be afraid to spend it unless they found me and I only had half left, and only two days to find the rest.
better just give it to me then, Im only down the road a bit and it will be a great weight off your mind. No amount of money is worth your health , etc etc..
