> What right does a Flock camera violate?

The first amendment, fourth amendment, and the fourteenth amendment of the US Constitution. You should read it.

Can you name the specific right?

For the first, assumably you think you can’t be observed coming or going from a riot? That’s not true.

For the fourth, a Flock camera existing is not inherently a search, just like how a database of cell records is not unconstitutional (Carpenter, Chatrie, Katz).

Is the 14th just a nebulous due process argument? Again, the camera existing is not an unconstitutional, see 4th.

You should read them again.
