I find it very hard to believe that any police department and school system would trick kids into this kind of exercise. Not saying it’s not possible, but I’m suspicious. See a message here that is supposedly from the police chief (fourth post): http://www.alipac.us/f9/true-false-swat-team-performs-realistic-hijacking-drill-real-children-285835/ While I can’t find any official press release or other info on the police department’s website, I still think it’s more plausible that the television report was incomplete than that the kids were tricked, if for no other reason than that schools tend to do everything they can to avoid potential lawsuits, and doing this without the consent of the kids would be like a recipe for lawsuits. Of course, all this leaves aside the important question of whether or not such a drill is ever necessary, even with the consent of the participants. I suppose it’s also arguable whether teenagers are capable of giving informed consent for something like this.
