The vast majority of mass shootings take place in places where guns are not allowed. This seems to indicate that guns are actually good at preventing mass shootings.

Finland and Norway have restrictive gun control, yet they're responsible for far more mass shooting fatalities per capita than the USA. How do you explain that?

Do you really think someone who's prepared to DIE gives two shits about your laws? Did you also forget that murder is already illegal? You want to criminalize the criminal so he doesn't commit a crime? That worked so well for drugs, nobody ever uses those anymore...

Laws only affect those willing to follow them, and guess what? Criminals by definition aren't.

Also can people stop acting like 'the black market' is this foreign place that you have to know a secret code to get in? For christ's sake, it's 2015, you don't even have to LEAVE YOUR HOUSE to buy an un-registered, unmarked, illegal firearm, but sure, the people buying them legally are the problem.

Bad people will always have guns, suggesting a ban is basically telling everyone who has defended their own life with a firearm (myself included) that they deserve to be dead, and well, my response to that would be pretty vulgar.
