Ah, good to know. And yes, that is unfortunate, as I also assume the permissible sources will be too dated to keep up with the adoption pace of Flock and other ALPR/surveillance cameras out there. But I will survey those permissible sources to check and then drive to validate the few I didn’t already physically drive by.

I've been working on a project to pull in open source data from Wigle.net for wifi & bluetooth artifacts to overlay potential cameras onto Google Earth and then validating camera location and direction via street view or physically driving to the location if I can't find it on Google Earth.
