Hey, if I had killed someone every time I saw a really bad movie, I would have been the most succesful mass murderer in the history of mankind by now
Countless movies have provoked countless numbers of people. Because of religion, history, sexuality, violence, etc. So what exactly is your point?
Regardless, feeling provoked or offended by a movie is fairly retarded anyway. If it bothers you that much, you can always just, you know, not watch it.
Euhm, seems to me that the movie is the entire reason this thing happened (that's how I read it anyway). That makes it part of whatever discussion you're going to have, whether you like it or not.
Besides, who said something about the movie being right or not?
But yeah, there will probably be repercussions. And, not entirely unimportant, a major part of the American population (possibly even Western population in general) will approve of them. Freedom of speech, religious fundamentalism linked with violence, etc. Easy enough to (ab)use all this...
