"Leftists" ??? I didn't see much leftist in the simplistic, poorly thought out nonsense in the article.

None of the suggestions in there will eliminate school shootings overnight. Metal detectors won't stop someone on their way in to kill people.
Drills won't stop the shootings - they might save a few people, but they won't stop the shooter.
Arm more people -yeah, right. Lets put more guns in the schools.
Show the consequences - do you really think that someone going into a school with the intent of killing people really gives a shit about the consequences?
He's already accepted that reinforcing doors and windows doesn't work.

No common sense Americans can deny the effectiveness of this shit? Is Kevin McCullough real or is this a spoof site?
