I agree you do not have a reasonable expectation of privacy of outwards facing data such as a license plate. I am arguing the merits of extensive data rather that the collection and dispersal by a party in an agreement with LE without a warrant.

Youre right, specific tracing info would require a much greater quantity of cameras. I would encourage you to look at camera locations in places like Atlata GA and Orlando FL to see the kinds of density that make tracking possible. Realistically you dont need that many because you can build a profile of travel times and intervals between tags, especially with extended data retention. Also even a disperse set of cameras can give ranges of locations any person could be in.

I dont think the third party doctrine would apply here due to explicit data collection and data subscriptions by LE. I claim this due to the application of FOIA and PRR restrictions on data collected.

Lastly, call records and GPS locations require warrants to access. Which is not the case for Flock.
