*NOTE* Additional tragedy was prevented because someone on school property was legally carrying a gun.
So several important points ignored by the “journalists.”
1. Race of perp.
2. (just guessing here) Perp was not in legal possession of firearm. Gun laws would not have prevented this shooting.
3. Perp violated gun-free zone.
4. Guns save lives.
I doubt if many high school students are (or should be) of an age to legally purchase or be in possession of a pistol of any kind.
