That's a ridiculous assumption to make. Every screening process has flaws. I would expect the majority of the people at MIT to be really brilliant, but there are bound to be at least a couple immature idiots that slipped through the cracks.

It hasn't been proven that the person was associated with MIT, but at the very least, I'd be chasing down anyone who had a potential grudge against the MIT employee that was accused of being a gunman. There's other ways that a person could have known his name, but it does seem kind of suspicious. Unless more information gets released, there's nothing to indicate that it wasn't.

MIT hacks are not supposed to be damaging in any way, at least according to lore.

With anything as elite as MIT there is bound to be a few very self centered narcissists.
