Let's get one thing clear. There is no such thing as 'gun violence'. There is human violence. It is a part of our nature. Always has been, always will be. Regardless what the left professes. Mr. Mayor, the gun would have done nothing. It is an inanimate object. (for those liberals who don't understand that means the gun has no life nor capability to move on it's own). When will you get it through your thick head that criminals and those with an evil bent just love 'gun free zones'. If the principal had been trained and had a gun perhaps several more children would be alive today.
