Gun Control

Can someone kindly provide a non-biased, definitive source showing that gun control has a negative effect? All the ones posted here are from NRA or some other obviously biased source with unbacked allegations.

I don't even know what this here thread is all about, but I'm anti gun control! TEXAS #1 USA USA USA WOOOOOH GO DALLAS!!!!

Penises don't rape people. It is people with penises who rape people. Or penes if you want to get technical.

TEXTBOARDS ARE SHIT :EDDD
