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.
It's self explanatory.
As is the fact that the courts have ruled (multiple times?) that they have the right to do this at the borders.
They just make it a probable cause. Problem solved for them.
It is not self-explanatory how to define the weasel word "unreasonable"
I’m always confused when people say this. It’s vague as heck! That one little word in there, “unreasonable,” makes it completely up for interpretation.
Haha, as if the constitution matters anymore.
It only self-explains what it says, not what the police actually do.
