> What freedom is being impinged?

Freedoms guaranteed by the 1st amendment:

Freedom of the press - by harassing or criminalizing journalists who seek to expose gov or politicians who do wrong.

Freedom of assembly - license plate readers have been used to mass collect plates from people attending political rallies for mainstream candidates.

Freedom of speech and petition - tracking and harassing people for political speech or peaceful protest.

Under the second amendment:

Right to keep and bear arms.

See feds slurping up data on gun show attendees. Doing something that is a basic right should not land you in a gov crime database.

Under the 4th: Protection against unreasonable searches and seizures. Knowing where someone is at all times is an unreasonable search.

And of course the supreme court has ruled that there is no basic right to privacy in the constitution, when they overturned roe v wade, but i strongly disagree with that ruling and believe it was not fair or consistent with the intent of the constitution.
