So, since you obviously know what every single teacher in America should be allowed to do, I've got a question.
You believe that arming teachers is a bad idea. Okay, I don't agree with that, but I can respect that you have a different opinion than I do. Obviously, you believe that police should do the job. Okay, I get that, too.
The tragic, inescapable reality is that, in Texas, the police didn't do their job. They waited for over an hour to confront Ramos. During that time, Ramos killed 21 people.
My question to you is this: How would having an armed teacher have been a detriment?
Do you really believe it's preferable to allow a crazed gunman to continue his shooting spree unabated? Because that's essentially the position you've taken, and that's why no one here believes you're even remotely interested in protecting the children you allegedly teach...
