@Ragman,
I just wanted to get the point across that the problem is really not with guns per se.
I can see politicians putting a ban on all automatic and semi-automatic weapons for use outside of military and law enforcement and limit the number of weapons an individual could own to one or two after this highly tragic incident. However, beware if that were ever to happen, ss soon as the legislation hits the table, folks would go out of their way to hoard the big buns while they are still legal.
Even if this stricter gun law passes, you assume that there will not be a black market for these assault rifles.
Mexico has one of the toughest gun laws, but that hasn't prevented the gangs and criminals from attaining these assault rifles from US, China, Russia,North Korea, etc etc (even if US is taken out out their trading networks they still have alternative dealers to attain them from).
