There are lots of problems with carrying concealed weapons. First of all, do you really want everyone who has passed a government exam carrying a weapon under their clothes. Just because someone has never commited an offence doesn't mean they aren't capable of doing so. Also having guns in the country means they are easier to get, not every gun seller has scruples either. Look at Columbine, those kids passed for gun licnense and K Mart sold them the bullets. Also there is no point to a handgun except to kill people. They are useless for hunting, and anything beyond "self defence" and self defence in the US is bullshit anyway, just because someone steps on your property or even smacks you across the face does not give you or anyone else the right to take their life.
