You speak of laws in a lawless regime.
I would say a lawless federal regime. Which is expressly why I said at the state level. And while the current federal regime wants to involve itself with local police matters, counties and states are very equipped to stop such unconstitutional antics.
States certify local police departments, so they must obey state rules. Importantly, some states are already moving in the direction I propose. And not only for de-paramilitarization.
The Arizona legislature is proposing to change state law to make electronic evidence obtained without a warrant inadmissible in state courts. They don’t care if the NSA, the FBI, the CIA, etc., think it is fine and dandy, and have it approved by FISA courts and bureaucrats. It is not admissible evidence. Importantly, neither are its derivatives.
This means that if the NSA tells some police department that some Juan is a meth dealer because they intercepted his phone calls, they have effectively killed that arrest.
