It's that tricky part about needing the warrant to describe the places to be searched and the people or things to be siezed.
So, people are to be SECURE.
"The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, "
SHALL NOT BE VIOLATED. SHALL NOT BE VIOLATED. SHALL NOT BE VIOLATED. SHALL NOT BE VIOLATED.
SHOULD the search be reasonable, a warrant is necessary, affirmed by oath or affirmation of propable cause (not POSSIBLE CAUSE), describing the the places to be searched, or the persons and places to be siezed.
See, beucase the Brits used to bust down colonists' doors (without reasonable cause), arrest people (without reasonable cause), and even make up crimes after the arrest (ex post facto).
Oh, and there it is again, police will arrest police, and prosecutors prosecute prosecutors. These poeple are co-workers, teammates AND FRIENDS. sheesh.
