The argument is not about warrants, in every case, but about probable cause, in every case, which Carroll says you have to have.
Ad hominem. Thank you for conceding.
Carroll says IF you have probable cause, then you do not need a warrant to search AN AUTOMOBILE. One does not need probable cause to conduct a search at an airport. (Please see: United States v. Aukai, 497 F.3d 955 (2007)).
The fact is, despite what you keep insisting, Carroll says nothing about the various other exceptions that exist to the warrant requirement or searches that require less than probable cause. Please see: (Terry v. Ohio) (protective frisk with reasonable suspicion) (New York v. Burger (Administrative Searches) (Please also look into the exceptions for: exigent circumstances, hot pursuit, searches incident to lawful arrest, seizures in plain view, inventory searches, border searches and roadblocks.)
U MAD BRO?
