Again, don't believe everything you see on tv. "Hitmen" are usually tweakers looking for their next fix. The suave, debonair, master-of-disguise and kung-fu ninjas only live in the minds of Hollywood screenwriters.
Most murders for higher are done for a few thousand dollars, which makes it even more pathetic, I suppose.
Not necessarily...
But you can bet the rent, the dead guy who shot himself was involved one way or another.
