> We're talking 1-2 officers who quickly glance inside your bag and maybe a metal detector you walk through, similar to the security at a football game. It's more intended as security theatre by the presence of officers to discourage petty crime than to catch terrorists.

So just for some security theatre I have to give up a lot of privacy, add to my travel time by waiting in a queue, pay a higher fare to pay for all these guys? I'm really glad we don't do this here.

I don't like people demanding to look in my bag, trying to frisk me or metal scanning (of course I have metal on me). It will make me feel less safe.

So then you have to deal with them when you come out of the metro :) It's only moving the problem. Better to make sure they don't have to steal by having a decent welfare system.
