No, no. The FBI planes have "Stringray" devices on board and pick up people's private calls and their IMSI IDs. They also have FLIR/high-res cameras. This shit is not "public" when they pretend to be a cell-tower to MiTM your phone.
Also, the very nature of these devices ensure that they capture data that does not belong to the suspect under warrant. Just because a suspect lives in an area near me, does not give them any right whatsoever to collect my data.

This is often not true. Many cases have shown evidence of being put together through parallel construction. It's easy to find damning evidence if you know exactly where to look, the phone conversation that leads them to the evidence is not required.
