ELI5: Why doesn't the 4th Amendment protect people from mass surveillance?
gpt
> The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.

There are a few key words here that were left open to interpretation. Notably things like "unreasonable" and "probable". If the courts decide that something is not "unreasonable", then it's fair game. Likewise, if they decide a situation gives "probable" cause, then it's fair game. Nothing on the Bill of Rights or the Constitution really elaborates on what those words actually mean, so courts have to decide as best they can what fits the intent of that amendment, and others.
