While Axon's system should be under the microscope too I don't think they have the nation wide cloud that Flock is doing and requires specific agreements to share data. Maybe that is getting abused to form a national database but I imagine it was designed so say a county sheriff department and local city PDs could share resources. I don't think most people are that concerned about things like that (though they should be), it is the nation wide surveillance that creeps people out. That and the stalking of course and both systems can be used for that.
