Actually if he was alive that would be really bad, because it'd give the media license to keep regurgitating the event in the media instead of letting it die- which does two things that work against us- it creates additional incentive for psychos to do these kinds of things because fame; and it also increases the fluff factor of such events, etc. Sandy Hook was as bad as it was, last thing we needed was even more reason for the media to keep talking about and lionizing that piece of shit in the years after. Look at what happened with the "beltway sniper" thing... do you think that they would have repeated the names of that guy and his kid 9000 times if the cops (or citizens) had shot both of them dead?
It's also hopelessly naive to think that they still wouldn't "blame the guns" etc.
