Not a LEO never in the service- I’d like to think if armed i’d hustle in looking for as much cover as possible on the way in but I’ve never been tested that way. Great Grandfather was a small town sheriff who had more than one successful gunfight and solo tracked down escaped Nazi prisoner. I hope I’m wrong but my perception of today’s law enforcement is drastically less heroic than 50 years ago. They train to have a huge force advantage and that isn’t available in these situations. It is embarrassing that so many teachers show so much more courage than the Leo’s here.
