If I have a reasonable suspicious that a crime (terrorism) may be committed and I see someone acting suspicious in the vacinity, I can shake them down for my own safety as well as the general publics safety. I'd rather see them use the term searching people that are acting suspicious.
But hey remove the cops if you like, it's not my subway. I don't ride on it. Still I hate to see people get hurt because someone decided to argue over terminology.

Well, if you've spotted someone who's acting suspicious, you've already established something the random search does not incorporate, and that is 'probable cause.' It's a whole different kettle of fish from just walking up to anybody in the street and requiring them to let you search their bag.
