It kind of sounds rather Gestapoish to me.
Was this guy a killer, did he shoot anyone or did he just rob a bank and injure no one. I don't see the urgency of it all. What was to stop this guy from having a shootout with LEO's when they approached him? He was the last person cuffed, so if he decided to shoot it out with LE, here's all these people standing around with handcuffs becoming targets.
So a bad guy is suspected of being in an Airport Terminal. Do they rush in, handcuff all the passengers, halt all flights/or not, search everyone which would take hours. Then ruin everybody's planned flight at the passengers expense. It can only just keep getting worse if not stopped.
