General Discussion
In reply to the discussion: If i am a teacher with a CCW and "a good guy with a gun" small enough to conceal [View all]Pat Tilman was in a combat zone and seemed to have been seperated from the rest of his unit. Mistakes were made, but war is hell. We are not talking about a confused combat zone, we are talking about a situation where someone who clearly does not belong has entered a building while carrying tools that can cause death and destruction.
As far as cops, unless the officer in question happens to enjoy shooting and goes to the range regularly, cops are generally poor shots that only qualify once a year. Training budgets are typically limited so that the Training Officers only give extra training to officers who need it and special training to officers that want it and are willing to work for free on off days to get it. This is from firsthand experience.
As far as those 90 rounds 15/90 (25%) hit what the officers were aiming at, as far as the other 75/90 experience says that they probably shot the building behind the suspect (just hope it wasn't a McDonald's), His car, the road, their cars, and each other. Experience being a similar case where over 120 rounds were fired.
The NYC incident is probably fairly close to the same. I don't have specifics as relates to that.
If a teacher is only as "well-trained" as those cops, one could expect 2/8 (25%) bullets to strike home and likely stop the threat. With the right ammunition load out, walls would be safe barriers.
Option # 2 leaves somebody that may choose to be armed and able to defend their students unarmed instead and at the mercy of any madman whether he only has a knife or something more dangerous.
