The usual criminally insane types, ie the right wing, are screaming “false flag” and accusing the “gun grabbers” of being overjoyed at this tragedy. No links necessary.

Obama is going to have to take some kind of action on gun control, even if it is only a gesture like the mostly useless Assault Weapons Ban. Owner licensing would help a lot, but real progress will require fundamental cultural change, a process that could take centuries.
