with all due respect, i don't necessarily believe that rosato intended for pentangelli to escape, but i still don't buy that the cops scared him. since i'm so young and virginous when it comes to the godfather, i ask a lot of what must seem like dumb questions on these boards and one of the most common things i am told is that these are professional gangsters, so we have to understand how they operate. i don't believe a man as experienced as rosato would shit his pants just because he sees a couple of cops. if he's a professional killer who was ordered to kill frank pentangelli, i think it would have taken more than that to rattle him so much he completely forgets to do the one thing he set out to accomplish, which was kill frankie.
