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.

Axon and Motorola also do a lot more to court state agencies who have grand plans of monitoring some highway corridor so their buddies at DEA/CPB/SMD/whatever can tip them off and their "drug task force" can make a newsworthy bust.

Flock by contrast courts local PDs who will catch a package thief or two but they really just want to have the drag net at their finger tips so that when some more equal animal's cat gets stolen they can walk back in time and figure out the short list of who could've done it.
