So, for some closure to the Sheriff Clarke aside;

And the Judge earlier threw out the rest of the suit;

If the deputies did not do what Clarke told them,and didn't detain the man, they did Clarke a huge favor.
The discovered text indicates that Clarke ordered Black be detained for a field interview. It matters because case law requires a "reasonable articulable suspicion", that the subject has committed a crime, is about to commit a crime, or is in the process of committing a crime, if he is to be detained.
Except for his butt-hurt threats against Black. The Court let that stand. Kind of poetic justice that his mouth put him in the box.
