Consider the 1999 massacre at Columbine High School in Littleton, Colorado.
Two kids, wearing long trench coats and armed with a variety of firearms,
including a 10-shot, Hi-Point model 995-carbine rifle and two Savage
12-gauge shotguns, came to school to bring death to their fellow
classmates. When it was over, 14 students, including the shooters, and one
teacher lay dead and 23 other students and faculty were seriously injured.
The shooters began their carnage in the front of the school where a school
resource officer pulled up and engaged them in a gunfight. He started out
well (one report said he hit the magazine of one killers carbine) however,
he quickly ran out of ammunition and had to pull out, leaving the school to
the two most horrendous juvenile mass-murderers we have ever seen. If he
had had a rifle in his vehicle and had been trained to use it, do you think
the situation at that school might have turned out differently? Lt. Col.
