That wasn’t.
Luckily, no adults were armed or the shooter may have had to think twice.
Questions to the anti’s – Why didn’t this man obey the “no guns” rule? Would you say that gun free zones have lowered the number of shootings? If so, can you provide statistical data to back up your assertion?
Finally, why should I, as a law abiding citizen, be stripped of my right of self defense simply because I’ve crossed an imaginary boundary? I’m armed around children all the time at parks, churches, malls, playgrounds, etc. Why is a school off limits to me?
