cameras to me eqal wiretap on all the phones = monitoring all ip traffic things that normally need a specific target and a warrant from a judge to be allowed.

Then that's a bad equasion.

Those other things - they apply to things where you can exclude others. Where you can have privacy.

You can refuse to open the trunk of your car to an officer - that's private. To open it, he must comply with the laws pertaining to the 4th amendment.

If you have something illegal sitting on the back seat of your car, and he can see it, then he's in full compliance for arresting you based on the sight.

Cameras in public do NOT equate to wiretapping private conversations.
