Having a neighbor who is a concealed carry instructor, I get that those who have them are trained; however, even if that person wears, or used to wear, a badge, I don't trust them. Especially in a situation where there's an active shooter. This will turn one person with a gun, into two people with a gun, one of which responders don't know anything about. Furthermore, having been in a high school with a fully loaded police officer, I still don't trust them. One time I asked about why the officer gets to carry a gun, and he replied, "Because if things get out of hand, I can shoot your a**." That man shouldn't have been an officer of the law, let alone be trusted with teenagers. And since one bad apple spoils the whole bunch, that one officer has forever jaded me about armed officers roaming the halls of schools.
