I don't know if axon does it, but the future is going to be mobile ALPRs. Uber drivers going around scanning every plate, selling to police, and helping predatory auto lenders repo cars. The latter is already being done, so it's just a matter of time.

Practically, axon cameras aren't nearly as ubiquitous as flock's, thus reducing the leo's dragnet capability. I'm sure the feds will successfully try to get access to this footage as well.
