Feds used FISA, possible stingray to spy on Giuliani-connected businessman

So this article came up that has me wondering....

One of the businessmen accused of conspiring with associates of Rudy Giuliani to make illegal campaign contributions argued Thursday in federal court that the government is trying to cover up the "warrantless and unlawful electronic surveillance" it conducted in its investigation, including possible "stingray" technology to track cellphones.

We have had quite a few threads here about stingray....Baltimore was one I remember.

Odd this is coming back up....wonder if it is connected to ShotSpotter as well....

Is this the hi-tech ShotSpotter/Stingray you're referring to?
