Sure, but I don't think we can make the Netherlands police in charge of our largest surveillance network.
Flock is despicable but after all the documented abuses of the system (assuming you don't accept that the entire system is an abuse) were enacted by cops (read: public officials).
I don't think a law making only ICE/FBI/etc able to access the data will do much to slow the rapid expansion of the surveillance state
Believe me, I’m as opposed to this all as you, but playing steelman for a possible solution if it really is helpful to law enforcement and civil society to have these cameras…
What if you made the data only recorded for flagged license plates, for example? Where all information is discarded at the camera-level (not even sent to remote servers) unless it matches a specific target given by police with an expiration date, with an audit trail for every entry, and manual blind-solution human review to confirm any matches before an event is even recorded
