Ok I slightly misunderstood the original post. You were talking more along the lines of mass shootings. My perspective was that of the more low key crimes i.e. Home robbery, murder, or bank heist. (Little bit strange categorizing those last two under low key crimes) see if someone really despises another person, they have ways of illegally acquiring a gun and shooting said person. Now I see you made an edit about not being able to shoot someone before they shoot you in a home robbery or self defense situation. In [b][u]Most[/u][/b] cases the owner of the home can hear a robber rattling doorknobs or breaking in windows or kicking out the door, allowing the owner to grab their weapon and assume a defensive position. As far as crimes such as bank heist, there are multiple accounts of a single concealed carrier (or multiple if such is the case) taking down the heist long before the proper law enforcement can arrive. Take away those carriers and you have a much messier situation, maybe the criminals get away before the law enforcement can arrive. Or worse, the law enforcement does arrive, so the criminals are covered and start taking hostages resulting in a shootout that can result in loss of innocent life. These are just three examples and I hope you can see where I'm coming from, and that mass shootings are not the only crimes committed by guns. Have a nice day. :)
