We have to consider the possibility that they are not.
The example of Beslan cannot be ignored.
On the first day of school in September of 2004 in the Russian town of Beslan, approximately 100 pro-Chechan Islamic terrorists - many embedded as school workers -- seized over 1,200 children and adults in School Number One. While the details of the siege are quite disturbing, they must be absorbed in order to properly understand the threat before us.Men, women, and children (including babies) were herded into an unventilated gym, where temperatures rose to 115 degrees. Hostages were given no food or water and women (and some children) were repeatedly raped. Adult and stronger male students were forced to help fortify the building; then shot without mercy; their bodies tossed out a second story window into the courtyard.Hostiles warned Russian Security Forces that if stormed, they would detonate the building and that for every one in their ranks killed, 50 hostages would be butchered. Armed guards stood amongst prisoners on "deadman switches" which were wired to explosives. Others wore "black widow" suicide vests, which could be triggered by remote control at the whim of their sadistic leaders. Doorways and stairways were booby-trapped and children were forced to sit on windowsills as human shields from snipers.
Could it happen here?
Of all the "soft" targets the United States has to offer these madmen, it's hard to find any more vulnerable than a school.And, as al-Qaeda has a history of plotting spectacular and awe-inspiring attacks, you'd be equally challenged to find a more inviting one.
