Mine never leaves my side when I'm carrying and it's always concealed. Leaving a firearm out unattended someplace is negligence and at that point you should have a serious conversation with yourself if you should be carrying at all. Not trying to start **** guys, it's just the way I feel because it is a responsibility and it MUST be treated as such. I still think training should be provided for teachers that want it and concealed carry should be allowed but that's just my opinion and I'm not pushing for policy.
