Sadly you are right.
I don’t like having to count on the cops being reasonable and honorable.
From a case in 1964, SC Judge Potter Stewart said:
“We may assume that the officers acted in good faith. But good faith on the part of the arresting officers is not enough. If subjective good faith alone were the test, the protections of the Fourth Amendment would evaporate, and the people would be secure in their persons, houses, papers, and effects, only in the discretion of the police.”
