Hm, that is pretty interesting. I've heard that everywhere.
I feel like something that can shoot that fast shouldn't be given out. You can defend yourself from an attack with a pistol or something, unless they have a gun as well, which may make it harder.
However, I feel like at this point it's too late to change much. People will have these guns regardless of what we do. So even if a ban on guns occurred, a lot of people will probably find a way around it.
