People are not being searched - only backpacks.
So .. I hope you enjoy being blown to bits.
But .. this whole thing is an offensive play .. in other words, if these bombers believe they will not be able to get into the tunnels, perhaps they will decide it's not worth the try.
We live in strange times. I don't like the thought of being blown to bits one bit, but I'd rather be blown up than wake up one day to discover that I'm living in a police state. Don't get me wrong, I respect a police presence but if this random search stuff starts getting out of hand, I'll be the first to scream 1984. There is a fine line between the order that Locke had in mind with security by the state and the "freedom is slavery" that Orwell could foresee in war fed paranoia.
