I think the issue with Flock isn't that they're a joke security wise the issue is that they exist. If you want to police somebody you don't have to police everyone. I'd argue watching my location at all times is unreasonable search.
I'm starting to think there should be a constitutional amendment specifying a right to privacy because the last few decades have shown they'll just keep pushing the boundaries otherwise.
If someone followed me around 24x7 with a notebook, transcribing all my movements and affixing carefully attached photos of me to every page, it would be called Stalking and I'm pretty sure I could win at least a restraining order against them in court.
I don't get why we treat this any differently. The only difference is they're not as obvious.
