Only thing that'll stop a bad guy with a gun...

Dr. Keynes Was Right:

There were at least 433 active shooter attacks — in which one or more shooters killed or attempted to kill multiple unrelated people in a populated place — in the United States from 2000 to 2021. Of those 433, guess how many were stopped by that Good Guy With a Gun? 12. That's 2.7%. And as the report makes clear, response to a motivated shooter, is almost never in real-time.
