All they have to do is cross-reference with the government’s EZPass records and do a FOI request for the NSA’s phone spying data and they’re gold.
A couple of comments on EZPass.
They have a similar system here in Houston, and they also read the transponders on the FREEWAYS (just look up, under an overpass).
Also, license plate cameras are so good now that there’s no need to even need a transponder. I have no clue how prevalent they are, where they’re located, or where the data is stored (or what, if any, protections there are), but I now assume that I’m being tracked from the moment that I leave my driveway.
(on the flip side, I wouldn’t mind having the system installed in the entrance to my neighborhood, might surprise some bad guys when the cops show up at their place before they even make it home with the loot)
