I wonder how many cases like this eventually broke the levee and the Concealed Carry movement started to grow.
Of course, the state of California still has not learned the very bloody and expensive lesson yet. This could have been yesterday, and we would not be surprised one bit.
One argument for magazine capacity limits is that a “mass” shooter will have to reload more often, allowing the “victims” to overcome the gunman, or at least escape.
IIRC, one mass shooter used limited capacity magazines because they fit better in his bag. Many people were still shot.
Also, a sheriff somewhere (out West?) ran tests with a person trying to touch a “shooter’s” shoulder during a mag change. The shooters were gun people and not-gun people. Most people reached the shooter after they inserted the new mag.
It did happen in the Portland school shooting, though. The assailant ran dry and 2 brothers who learned about rifles in Scouts charged the bad guy. One brother was hit once, but they took the bad guy down.
