The more I reflect on this, the angrier I become at the mother. Sure, it was her batshit crazy son that pulled the trigger, but seriously, if your child is some wild-eyed Icabod Crane-looking ****ing psychopath, it's probably not a good idea to have an arsenal of weapons sitting around the house that he has easy access to. They should have at least been in a safe he didn't know the combination to.
She certainly paid the ultimate price for her irresponsibility, but so many others did too. Or will in the future as a result of the shitstorm or hype.
I'm not mean; I just don't like you.
