Further tying into the school shooting thread, the common element is mental illness and the permissiveness with which it is treated. What does the field of psychiatry think it is accomplishing by pretending an appropriate treatment for someone might involve the deliberate surgical mutilation of their genitals, and a lifetime of taking synthetic hormones? And then as the icing on that particular cake, demanding that every facet of society must modify itself so as to enable these delusions?
Likewise with the CT shooter, and as far as I know just about all of the others as well. They all demonstrated mental problems earlier in life, and have history of being prescribed psychotropic medications. One thing most people don't realize is that since the 1970s it has been virtually impossible to involuntarily commit someone for psychiatric treatment. Most people seem to think it's still the way it was in One Flew Over the Cuckoo's Nest, and that if these guys were really so dangerous they would be strapped to a bed somewhere. But that is not so. They are given powerful medications that affect brain chemistry, with very little management of their treatment. I am wary of giving the state a lot of power when it comes to psychiatric commitment, because I know they will abuse any power they are given, but we also can't have dangerously ill people left to their own devices.
Both cases have in common this demand that society at large must be the one to give up things (whether individual rights, or a sense of normalcy) in order to accommodate the insane. So we must all be denied our 2nd Amendment rights because lunatics are allowed to wander society at large? We must all twist and contort words like "he" and "she" into their exact opposite meanings because some ill individual hates the anatomy they were born with?
