The fact police can go in and just look at camera footage without warrant proves your point precisely, officers have used it to stalk family members, etc.
I doubt any of that happened though.
also, since there has been a lot of talk of warrantless searches, 4th a, etc.... is there an expectation to privacy when out in public when one would be captured on a flock camera? like red light cameras already exist and some non-sworn pd admin is looking through your file to send you a ticket...
