Nice to see what I have to look forward to now when I get back.

I'm guessing I will just have to build a trapdoor into my packs when heading into the city from now on. Damned inconvenient, but I am not going to rely on them to keep me safe and secure.

Let me guess, these "checkpoints" are in high traffic areas, right? So if Mr. Terrorist were to get stopped, he would just light off his bomb right there, taking out about as many people as he would've on the platform, or in the train (actually, the train might mitigate some of the explosion, inducing fewer casualties).

The #1 spot in Baghdad for the BGs to pop their suicide bombs was at the gates/entrances to controlled areas. This is because it is a choke point where people are most concentrated. Sure, they would like to get their bombs inside, and they tried, but it was a great consolation to them to thump the gates if detention/discovery looked imminent.

Now that you mention it, I suppose the checkpoints are fairly well thought out. One cop stands at the turnstiles and directs people with bags to a table off in a remote corner of the station.

But there are still plenty of high-traffic choke points outside the turnstiles that would provide a high body count.

I rather like that... "No officer, I have no idea how that big metal spoon made it into my backpack. Guess its just one of those things."

The next thing they will require is a piece of identification showing that you are who you say you are, with an appropriate destination address on it.

"Comrade, you must show me zee papers!!"

Typical Bastogne response: "Nuts!"
