You are absolutely correct but you won't get anywhere here.

I have relatives who are cops and lawyers and city councilmen. No cop is sitting in a back room somewhere tracking all the cars on every street trying to do, uh, whatever it is people here are claiming they are going to do to them.

An obsessive stalker police officer that's angry at their ex girlfriend moving on and finding a new partner will probably not be interested in EVERY car, just the one she drives and the one her new boyfriend drives.

I won't speculate as to what your law enforcement family members may or may not be capable of when it comes to this technology, but I will speculate on what they will likely do if they found out about an obsessive stalker police officer that's watching their ex-girlfriend and her new partner using this tech: they will likely assist in hiding it so as to ensure that the optics of the justice system are not marred.

The reason I suspect they will behave in this way is not because they're bad people - but because they're likely normal people who are subject to normal influences and incentives. There will be no personal benefit, and significant personal risk associated with whistleblowing on this hypothetical officer, and so they will find rationalizations for why they shouldn't. Why it's fine to let this "one bad apple" go for the greater good of the optics of the justice system.

So it goes.

I also wonder what makes people think the cops are going to trust AI any more than anyone else. A mistake on bad information is even more dangerous for them and often makes national news.
