What part of the bill of rights protects your whereabouts in public from being recorded? Are you referring to this: "The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated"
You aren't being tracked inside your house. Nor is anyone doing a cavity search on you.
Now I agree "mass surveillance" is creepy, but we can have Flock without mass surveillance. If someone is kidnapped or attacked in a particular location the police should have the right to see what cars or persons were around there. How is that different from the police going around asking neighbors if they saw any vehicle or person leaving a building? That's literally what law enforcement has done in the US for over a hundred years. You know, a detective finding out from a homeless dude that "a guy in a red shirt left the building at 11:10am where the crime took place", and then someone else says "a guy wearing a red shirt ran into apartment 13B across the street at 11:15am" . DA takes the case and red shirt owner in apt 123b;We're okay with people convicted on flimsy stuff like that, but not surveillance that shows the perp's movements clearly?
We should make it illegal for surveillance to be abused or utilized to solve minor crimes. Only major felonies. Make it highly illegal to abuse it -- strong jail times attached, and also make any surveillance obtained information on minor crimes impossible to use. So if they catch you smoking weed they can't use that against you.
