isnt this only allowed in that you need a license to drive?
theres no equivalent where the cops camp a walkway and demand everyone show whats in their pockets
5G mid-band (let's go with the charitable option) has an effective range of up to 2miles.
So no big deal, just all 5G communications within up to a 12sq mi circle surrounding the vehicle.
Don't think that's exactly "targeted".
Legally, there's a debate to be had.
A telescope on a hill that can see everything within a 12sq mi circle Vs a "google maps" type 360 panorama lens on the same hill.
Live only versus 24/7 recording, filtered (only pointed at one house of interest / only logging specific devices / only logging a network of devices that interact with devices of interest)
The question re: "targeted" goes to whether it's opened ended recording of everything, or filtered and targeted sifting out of warranted subjects.
