Lawful stop? No. Remedy? No.
The core issue is that the judiciary's (and your) presumption of reliable and trustworthy law enforcement behavior is not valid. This is a LEO 'company culture' problem which has always existed (formerly a racial problem, but now everyone's problem now that we're not doing that any more).
I'm not sure what the answer is, other than people need to learn what has happened in the ghetto for the last 200 years, then accept that they're next.
