Part of why we have never been invaded is due to the fact that a large majority of Americans have their own firearms to defend their land. Guns are capable of a lot of damage no matter which model, but we must remember that they are tools. In the hands of a responsible gun owner, most won’t use their firearm unless they ultimately have to. But allowing Psychopaths to purchase any kind of firearm is just asinine. A good guy with a gun can stop a bad guy with a gun, sure. But 9/10 times that bad guy was able to gun down someone before our “good guy” could do anything. Our good guy may be a hero and our bad guy dead or in jail, but the innocent bystander didn’t have to die or get shot. Keep guns out of the hands of the wrong people.
