I'm in the middle of a suit against them for harassment received from surveillance employees. Can't say much more than that (active case), but it's extremely common. The methods used once surveillance is discovered are deliberately made to be so unusual that you're either terrified into silence or are afraid no one would believe you, so that the operation can continue.

I dunno. They applied COINTELPRO tactics from the 1960s to take down the Sicilian Mafia in the 1970s once Hoover was out of the picture. One of the best ways for cops to get some credibility is to bust somebody who deserves it.
