Yes that's true. But the idea that there's an entity which can "magically" drum up a precise interdiction point where probable cause should be manufactured by law enforcement isn't good.

If a police officer wouldn't suspect you of a crime without the special instructions given to him by someone with access to sensitive information then you've just done an end-run around probable cause. Sure the police can manufacture probable cause to stop and search nearly everyone all the time. But they don't because they'd prefer to have some kind of actual probable cause because that gives them a much higher chance of not being on a wild goose chase. Subverting this limitation due to resources also subverts the even application of the law which is a bad thing.

The idea that drug dealers can't be caught the old fashioned way and spying on all American citizens in order to catch some people engaged in largely victimless criminal activity is laughable at best and terrifying at worst.
