This thread got seriously derailed, like, 39 or so pages ago but let's get back to talking about the original question.
What can be done to prevent these situations?
I admit to not knowing the entire situation but I'm hoping the LE in our midst will chime in. I realize, too, that since they were in all likelihood not present either in the Texas incident, that their first hand knowledge is also somewhat limited.
I'd like to look in particular at the 77 minutes that LE on the scene held back? Like Muddyboots stated in the original post, this isnt about bashing LE but merely an attempt to learn.
It seems like one of the other shootings, maybe in Florida, also had a delayed response? What was the reasoning?
Personally, I am an advocate of allowing any school staff who has been vetted and trained to be anonamosly armed.
Any thoughts, especially from LE?
