It will go down in the statistics as yet another "child" killed by a gun and be used as another example why guns should be outlawed by the anti-gun types.
I am surprised that the Dallas paper reported it as they did. Usually the liberal press doesn't want to mention that a good guy successfully protected him/her self using a gun. They usually don't want to print anything that may sound positive with gun ownership.
It is always a shame when someone dies, but that is the risk one takes when breaking the law. Better the bad guy than the true victim. Another good example for concealed carry.
