Well, we need laws and oversight to stop these actions. Do you realize that people use phones to stalk innocent people? And yet you probably have a phone. Why is that?
Analogies are distracting. They are rhetorical junk food. Make an argument directly supporting Flock cameras - don't just say "it's like phones".
Saying "surveillance is bad because it has been abused in these instances" is not a particularly compelling argument because it doesn't talk about the "cost for value, downsides for upsides, risk for reward" aspects of flock.
Just like you say, it still gets abused both within and outside the government (eg. Salt Typhoon) because surveillance inherently threatens society.
It's unfair that criminals can opt-out of surveillance, while Senators and CEOs cannot.
Do you think this hasn't been tried?
We have laws on stalking. We've tried to rein in cops.
