Ever notice how all these shootings happen at places where the populace is disarmed? Schools, College campuses, theaters,....they never happen at police stations, gun stores, or any other place that has a strong fire arm presence.
These tragedies could be prevented if they had an armed prescence on their grounds, I have the right to bear arms and I conceal carry, it is within my right to do so and protect myself if need be. Why are teachers and professors not given the same rights? Why are they being forced to put their student's lives at risk by not having the ability to protect them?
Bottom line is that it's simply wrong to deny teachers their right to bear arms and protect themselves and their kids. No one would shoot up another school again if their were armed teachers on the campus.
