OK, first of all, you took your son to see a movie with Paul Giamotti and Vince Vaughan and you're worried about violence?

I am far more concerned that my son will mimic the crude, inappropriate humor in a movie like this over picking up a toy gun (which he does not own) and emulating a violent exchange.

Secondly, the war is a reality. Had you taken two seconds to snap out of your sheltered little life, you could have used that moment to educate your son that there are indeed people facing realities like that overseas every day (My sister and the loved ones of several on this site have faced this personally). You aren't doing your son any favors by trying to hide things like that from him.

As for the Bruce Willis trailer, I looked up one of the 3 trailers that is currently in ciruclation for this movie. Now, obviously I don't know if I watched the same one as you, but I saw nothing that inherently bad and the movie has a PG-13 rating. How much worse could the other trailers (or the movie itself) be?

There is no way that any company will be able to please everybody and if your sensitivities are that high, perhaps going out to the movies with your child is not a good idea for you.

I think that if you are personally this offended by trailers and ads, perhaps you should consider waiting until the movie comes out on DVD so that you can control what your son watches 100%.
