The New York City police will begin randomly searching people’s bags on subways, buses, commuter trains, and ferries.
“The police can and should be aggressively investigating anyone they suspect is trying to bring explosives into the subway,” said Christopher Dunn, associate legal director at the New York Civil Liberties Union. “However, random police searches of people without any suspicion of wrongdoing are contrary to our most basic constitutional values. This is a very troubling announcement.”
If the choice is between random searching and profiling, then random searching is a more effective security countermeasure. But Dunn is correct above when he says that there are some enormous trade-offs in liberty. And I don’t think we’re getting very much security in return.
Especially considering this:
[Police Commissioner Raymond] Kelly stressed that officers posted at subway entrances would not engage in racial profiling, and that passengers are free to “turn around and leave.”
“Okay guys; here are your explosives. If one of you gets singled out for a search, just turn around and leave. And then go back in via another entrance, or take a taxi to the next subway stop.”
And I don’t think they’ll be truly random, either. I think the police doing the searching will profile, because that’s what happens.
It’s another “movie plot threat.” It’s another “public relations security system.” It’s a waste of money, it substantially reduces our liberties, and it won’t make us any safer.
Final note: I often get comments along the lines of “Stop criticizing stuff; tell us what we should do.” My answer is always the same. Counterterrorism is most effective when it doesn’t make arbitrary assumptions about the terrorists’ plans. Stop searching bags on the subways, and spend the money on 1) intelligence and investigation—stopping the terrorists regardless of what their plans are, and 2) emergency response—lessening the impact of a terrorist attack, regardless of what the plans are. Countermeasures that defend against particular targets, or assume particular tactics, or cause the terrorists to make insignificant modifications in their plans, or that surveil the entire population looking for the few terrorists, are largely not worth it.
