Average American have better arms and are probably better shots then the terrorists, any takeover of an American school would not last long, the local Sherif would in short order have an over whemling force of men willing and able to take out the terrorists. It is the American way.
Too late if the school, or a bus full of kids is wired to blow. One move, and you get Russian redux.
It didn't happen during Columbine.
"the local Sherif would in short order have an over whemling force of men willing and able"
I think you are kidding yourself. The local sherif and cops be be in the way, stopping a rescue until they can do it safely after the perps have run away. They would arrest you for trying to save your kid.
The local sheriff? You've got to be kidding. Remember Columbine, where the local sheriff and his gang sat outside eating donuts while a teacher bled to death inside?
This would NEVER happen in the Minnesota metropolitan school districts - ever. As one poster already said, in the RAT enclave of the cities, they identify with the terrorists already. A couple days after 911, they held a candle-light ceremony at the capitol and had an Islamic speaker and they prayed for peace and no more violence. An attack might wake up a few, but it would not change the nitwits in the city core, local leadership and it sure as hell wouldn't change the tone of the Red Star Tribune. Remember, we gave the nation Paul Wellstone and we have openly Marxist weasels in our government and legislature. They would cave like France and mewl like kittens for peace and understanding.
