I have nothing against LPR's (License Plate Readers) per se, I thinks their usage by
local law enforcement for
targeted searches eg, missing persons, stolen vehicles, criminal suspects, etc is fine. Of course to do that the LPR's are continuously collecting data just as any other surveillance camera system does. Thing is, with 'normal' cameras the pictures/video is only accessed when something happens in the local area. My problem is with Flock's data being used in very broad searches by agencies outside of the local areas or states for blanket non-specific target searches - that is going way beyond reasonable surveillance.
Per Flock's general ToS, by default Flock's data is held for 30-days or per local regulations. After that it is
moved to trash and not freely shared with contracted agencies but is NOT completely deleted.
Trash files are only totally deleted after 5 years. That last bit is what really has concerned people up in arms because it means that law enforcement agencies can request (with warrants) that searches can be tracked
for as far back as 5 years. Do note that with active cases the clock is stopped until a case is closed.
Something to note is that recently Ring (doorbell cameras)
canceled their contracts with Flock because of public backlash. The idea of consumers being able to opt-in for LOCAL neighborhood targeted usage of it to find lost pets or people who have wandered off - fine. In those cases the parties concerned submit a picture of the missing pet/person along with a defined local area search radius and the Flock systems search using only that criteria.
Allowing Ring camera footage to automatically be available w/o consumer permission for all interested parties to use as part of Flock's data for an all-areas blanket search - terrible idea. That is what caused the backlash of many MANY Ring subscribers cancelling their cloud storage subscriptions which is Ring's main money maker. Losing that revenue stream is why Ring cancelled all consumer contracts with Flock.
Do note that private businesses, HOA's, etc still can allow their data to be used in the Flock database after opting-in.
