If you were inside a restaurant and a guy walked in and started systematically shooting people one-by-one would you rather be holding a pistol or a fork?
Let's take the Luby Restaurant mass shooting in 1991. George Hennard walked into the restaurant armed with a Glock 17 and a Ruger P89 - neither of which, by the way, are assault weapons. He shot and killed 23 people, some with kill shots to the head, and wounded another 27. He took his time. One of the survivors was Suzanna Hupp, a politician, who later went on to be a leading advocate of the right to carry concealed weapons. Hupp was eating at Liby's with her parents, both of whom were killed. According to her own testimony when the shooting started she reached for her pistol which she then remembered she left in the glove box of her car before entering the restaurant for fear of violating state weapons carry laws.

And yes, there are other examples where mass shooting were stopped.

We could keep going with examples on both sides where shootings were stopped and where shootings were not stopped.
The question is: If assault weapons were made illegal would this prevent mass shootings? I say no only because 1) there would still be assault weapons on the black market available to mass shooters and 2) one does not need an assault weapon to kill lots of people.
I am sorry to ask but do you think a shooter has an easier time killing young children in a school because he/she has an assault rifle? The answer, as those of us who have experience with weapons will tell you, is no.
So the next question is: If all weapons were made illegal would this prevent mass shootings? I say no again because of #1 above. The only impact would be to prevent a guy like me from legally carrying a concealed weapon.
Then the next logical question is: If a guy like me legally carrying a concealed weapon is at the location of a mass shooting would that stop a shooter? I say yes but only under the right circumstances.
- If I was in a dark movie theater and a shooting started would I be able to intervene? Probably not.
- If I was in a classroom and a shooting started in campus would I be able to intervene. Probably yes.
- If I was in a restaurant and a shooter walked in would I be able to intervene? Probably yes.
- If I was on the street and a shooter with a rifle had a sniper position in a building would I be able to intervene? Probably not.
I answer these questions as a guy with a lot of weapons experience, both military weapons, assault weapons, as well as civilian weapons. I don't own an assault rifle and I don't hunt with guns so I actually have nothing personal to lose in an assault weapons ban.
It is just real-world logic to me.
