I was reading Colin Goddard's op-ed where he pleads to keep everyone defenseless, because it worked so well for him, when something really stood out and compelled a rant out of me.
From the article:
"I barely had time to make the phone call. Anyone who thinks I could have gotten to a weapon and shot somebody I never fully saw watches too many movies."
Colin, I'm going to give you the benefit of the doubt, that you aren't intentionally trying to spread misinformation, but this statement is ridiculous and insulting.
The time required to get your phone and dial it is arguably similar to drawing, aiming, and firing your gun. I say "arguably" because I think most people who have done both would say the phone is actually much slower to operate.
My personal experience in non-threatening situations shows that my gun operation is orders of magnitude faster than my phone operation. I have no reason to believe that relationship would change under other circumstances.

There are many, many Colin Goddards out there, especially on campus.
Locate these people early in case the need arises for a human shield
when you begin your counteroffensive.
