Check your town's website for correspondence with your state's chapter of the ACLU in regards to Flock cameras. If your police chief (not an elected official) is installing them then contact your local ACLU chapter about it. These are 4th amendment violations.
Yes. Let's restrict police and take away every possible tool they can use to solve and fight crime. Not all criminals are bad criminals. They don't use Flock to spy on their ex-girlfriends but every cop in America has done it.
At least according to the internet which knows everything.
To the contrary, little of what Flock does would be restricted by the 4th amendment. The cameras are in public, and neither the government nor individual citizens need authorization to film people in public.
Many Flock cameras are also privately owned, too.
