Wow. Yeah, this guy should be arrested or at least fired. I guess he must have failed gun safety 101? What happened to the whole "Always treat a gun like it is loaded" bit? To me, that's enough grounds right there. Simple basic stuff. Bringing a loaded gun to school for safety reasons and have a concealed carry permit? Fine. Waving it around a classroom for whatever reason without unloading it first and double checking it? That's just stupid. I know you can say it was a mistake, but it's a mistake - as we see in this case - like forgetting that a red light means stop. People can easily get hurt, and you are definitely at fault for it. If he only gets fired, he should be thankful for it. He may have meant well, but he screwed up on step 1.
