As Derek wrote this piece of tripe, he still did not know the full story. The shooter used an Armalite .223 semi automatic rifle. This was the precursor to the M16, the US military's weapon of choice during Viet Nam. The mother of the shooter was a gun lover who, by the time the full story gets out, had an arsenal in her house, just as gun lovers demand. unfortunately, those guns were available to a psycho kid. That darn media.
