This is something that I've said for awhile, the worlds a changing and there is nothing we can do but try to stop these deadly attacks from happening again. You must change the world, but we shouldn't allow the number of attacks to somehow normalize it in the least and we should always take these attacks with the highest degree of sadness and hope to be able to change something in the world to stop this from occurring again.

Who knows how to stop it though, it's one of those things that's tough if the people are homegrown - the only thing you can do is surrender some of your freedoms to the government for them to watch over and ATTEMPT to find a terrorist that is homegrown, though even then that may not work.
