I don't have any kids, but, would still vote no. Why? How would one possibly know if the Teacher doesn't have a chip on their shoulders as well? And, now being armed with a weapon of lethal potential, could change one's outlook, or how they would have (normally) reacted in the first place. It could apply to other devices as well. Haven't paddles been outlawed? Why?
If a teacher was going to go off the deep end, they have other weapons at there disposal like scissors, could just stab students. the gun is just a inaninimate tool, nothing more. The teachers with concealed carry permits in most states would have additional training, as well as being finger printed and a better background check then the average citizen.
Gun free zones is were all of these mass shooting are taking place, why is that? Maybe because the bag guys know there will be no resistance to there actions. I don't think teachers would be anymore dangerous in the school with students then the average concealed carry permit holder out in the general population.
The thing that gets me is why doesn't the media report on the shootings that are stopped by concealed carry holders, most times without firing a shot. Most of these mass murderers kill themselves when confronted by armed resistance. I also believe that the media is perpetuating these mass murders because they glorify the shooter, causing copycat's to follow suit. I think they don't report them because it doesn't fit within their agenda, since most are anti self defense. If the media would of tried some of the stuff they are doing now back in 1776 they would have to taken to the town square, and tarred and feathered.
Even senator Feinstein( the most rabid antigun politician had a concealed carry permit. Sounds to me like what is good for me isn't good for the people that elected me. These politicians need to be knocked of there high horse. To me they all need to be tried for Treason against the U.S. and serve no less than a life sentence.
