Are we so insane that we can actually have a news report about terrorism on CNN, talking to New Yorkers about potential terrorism, which is captioned "Could It Happen Here?"
And, can we please just stop being so stupid. If people want to blow up buses and trains, they're probably going to be able to blow up buses and trains. No security precautions compatible with a busy transit system are likely to stop them all the time. If people are willing to kill themselves while blowing up buses and trains, then they're probably going to succeed no matter what security systems are in place.
Security and intelligence may be able to significant reduce the likelihood of truly catastrophic terrorist attacks on transit, but if someone wants to walk into a subway car with a bomb and then set it off, there's really very little that can be done.
