To me this is kind of crap that will happen and keep happening as long as there will be humans. There are always nutters who are ready to support or copycat other nutters. Should we loose our sleep over the fact that some cold blooded idiot with agenda might kill you or your loved ones? No. We eventually all die and only few of us can actually decide when, how or why. Living is hard enough. Worrying about death is useless waste of time.
