I am an American gun owner. I am also a single woman who has been living by myself near large, dangerous cities my whole life. The gun doesn't leave the safe I have at a strategic proximity where I can reach it if I need to in a split second. Being part of a targeted demographic doesn't make me feel the need to pack heat everywhere I go. I just don't get that mentality.
In most cases I don't think a gun will protect you and others in the event of an active shooter. In fact, I think having a bunch of cowboys firing their guns off in hopes of hitting the assailant would make matters much worse. Anyone that tells you they can shoot well under stress and pressure with the intent to take another person's life has most likely never been in the position to do so. It's not easy.
In a perfect world where all gun owners are intelligent, calm, and responsible, guns could serve as a deterrent to people wishing to conduct mass casualty shootings. That's not the case and now all we have are a bunch of trigger-happy people going to Trader Joe's with a gun in their pants. I think intensive training and background checks are necessary to obtain guns and I am not in favor of concealed carry in 90% of places.
In Virginia you can obtain a gun if you can count your toes and cook toast. That's how a psycho recently acquired a gun to kill a young journalist and cameraman on live TV. Lastly, I hate the argument that criminals will get guns regardless. No scheiße, but it is still too easy for them to find weapons because we have so many guns around to begin with.
