Looks like the President is vowing to do everything within his power to prevent another shooting like this. That's kind of worrisome. For one, it's not his job. This is something that should be handled at the local law enforcement level first, then it should go no higher than the state level. The federal government has no business getting involved and trying to write laws to prevent disturbed people from doing disturbing things.
Did anyone else read or hear any reports stating that the shooter was autistic? I've also heard that the early reports of his mother being a former teacher at the school were false.
