Yep,
Take away the ability to defend opens the door for an aggressor.

Democrats are fine with armed people defending their money in the banks but they are horrified at the thought of having armed people in the schools to defend their kids.
Go figure.
Never try to use logic or common sense when trying to figure out how a Democrat's thought process works. It's all emotional hand-wringing and political correctness.

This is not a gun control or political issue. And as long as it's treated that way these shooting will continue to happen.
