The 5 or 6  US Supreme court decisions on justification for profiling seem to have been missed by Gearson and the radical leftists. Just seeing brown people driving was not enough, the Supreme's required  some other violation to have been observed to justify the stop  and questioning  that then led to inquiring about immigration status. The Federal court judge who charged Arpaio with contempt had a proven  personal animus against Arpaio, and Arpaio was denied a jury trial and the evidence against this Sheriff was insufficient (Dershowitz opinion) This was a political case, and the enforcement of immigration laws just as Arpaio was doing then is now National policy under a  DOJ, that follows the laws as written by Congress.
