My response was to a call to use retired police/former military. I was simply mentioning that just because someone is former police/military, it doesn't mean they're proficient.
I don't care who is carrying on campus, as long as they've passed the background check and can prove proficiency. If that includes teachers, then so be it. It's the proficiency I'm looking for. Not only must the shooter be stopped, but the person attempting the stop should be proficient enough to not cause additional casualties.

Agreed. And that possibility futher bolsters the lock down solution.
