Reply #2: My sympathies to the people of London

[HockeyMom]

as a New Yorker. I grew up riding the NYC subways. I have been trapped in packed subway cars in tunnels for mechanical breakdowns or fires down the lines. It's not pleasant. I don't even want to think what it must be like due to an act of terror. My prayers to all those Londoners.

That being said, I simply do not know how it is possible to secure a massive subway system against a terrorist act with miles and miles of tracks and tunnels, hundreds of entrances and exits, and above ground gratings. This isn't like an airport. Yes, I have been on the London Underground too.

Well, maybe now we will try to come up with some solutions.

Again, prayers to all Londoners.
