Just because someone can teach calculus does not mean that they can hit the broad side of a barn with a gun.
even if they could their shooting skills abandon them if someone is shooting back if they're not VERY HIGHLY TRAINED in a firefight situation ..
TOTAL BULL. You obviously don't know that most people with a carry license DO get training and DO practice regularly. If someone is trying to kill you with a gun, you will be trying your damned best to get them first. Skill or no skill, better to be able to shoot back and have a chance of hitting them than NO CHANCE AT ALL, besides, while you are shooting at the attacker, he will be tied down with your fire, backing off, rather than spraying the classroom killing the school kids. Just once show a little common sense.
