I don't know how true this flies, but from what I see on the news, and this is the only info I can base this on and if I'm wrong please correct me. It seems that from what I have observed, the efforts to erect and organize a "Memorial" could be better funneled into efforts to prevent these tragedies. Please don't take this as a slam on memorials. But it seems that everyone seems to come together in a moments notice to create these memorials. What if the same effort was put into organizing a neighborhood watch group or a neighborhood block club?
