How is Flock responsible in this case?? There may be cases where Flock is responsible, but I don't see it here.
Flock made the matches (Flock mass surveillance system) and let children (the police) play with them. The result is that citizens get burned.
I don't think ANPR systems should be held responsible for matching number-plates or car models. That's their job, and police have had access to such tools for many many years. It seems relatively clear that Flock was providing a commonplace technology here, that was misused.
If the police are children then that's the real problem.
