RE: I would not tolerate stop and frisk. Its unconstitutional.
Then you would not tolerate cops who give you a ticket for running a red light or going through a stop sign without proof ( only his word against yours ).
Try fighting it in court. Most of the time — YOU LOSE. The judge listens to the cops.
There goes “innocent until proven guilty”.
At least in stop and frisk, you aren’t fined for anything.
A policeman (or anyone else) witnessing a crime is evidence. And disputing such evidence is mostly a matter of conflicting evidence.
Your implication is that cops are mistaken or lie and that you don't get the benefit of the doubt. That is a separate issue altogether.
Stop and Frisk is not evidenced based at all. It is a gross violation of the 4th amendment.
