People in the 1700s would not expect all of their movements to be tracked and watched at all times. They would definitely take issue with this. The issue of their time was general warrants/writs of assistance which let the British search anyone anywhere at any time and take their property. [1]

The key issue there was the scope of the British power, not the fact that searches and seizures could happen at all. We wanted warrants that were reasonable and limited.

The issue is not a single security camera from a private bank. The issue is not a single cop in a car investigating someone. The issue is a national and searchable network of cameras where agents of the government can track anyone at any time for no reason at all.

The judge says the police need probable cause and a warrant for a search against an individual.

> Freedom from persistent, dragnet-style surveillance while in public is not a foreign concept in our society, and it is a reasonable expectation that society already accepts. This is the same expectation of privacy that the Supreme Court has continued to recognize in cases like Carpenter and Chatrie. Cell phones also move in public places where people can see you in plain view. But it becomes constitutionally problematic when law enforcement can indiscriminately and passively catalog your whereabouts over an extended period of time and then use that information for any purpose whenever convenient.

There's also: "The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people."

In the 1700s it was pretty easy to move into a private place and ensure nobody else was listening though too. We didn't have guard posts on every other corner writing down descriptions of every carriage and wagon that passes by.

Do you think the people in the 1700s would have approved of having police follow everyone around at all times in public spaces, taking notes? I think it’s easy to imagine how they would feel in principle, even if they couldn’t imagine the specific technology.

You need a warrant to tap somebody's phone.

Ben Franklin intercepted and published private mail in his newspaper

Watching people isn't the problem, it's the state requirement to be identifiable-- e.g. display plates (or, in some cases to not wear a mask in public) which is the constitutional issue. The privacy issue is downstream from that.

Frankly, the TSAs security theater should not be taken as an example of reasonable gov behaviour.
