When exactly was the Fourth Amendment changed?
Who is the warrant for, of not the one being served/searched?
What good is the warrant if the militarized stormtroopers have already kicked my door down, kicked my head in the dirt, and restrained me? Isn’t that the very process which the Brit army practiced on colonials which the founders wished to prevent?
The point of the warrant isn’t to appease or inform the target. The point of a warrant is to get a third party (nevermind that the judges are in cahoots with the cops) to agree there is reasonable cause to invade a person’s home and privacy under force of violence.
