It's pretty amazing how conservatives have internalized so much of the leftist pap from Hollywood movies and crime writers. Stop-and-frisk is actually a continuation of the policing practices of the time before Federal court rulings in the 1960's and beyond put a stop to them. Have a look at San Diego crime stats from before the 60's, and you'll see a pretty distinct trend.
You ignored my entire post. Nice job.
Simply lowering crime is NOT a legitimate reason for unconstitutional civil rights violations. Lots of heavy-handed and oppressive policies could result in lower crime, would you be OK with all of them, so long as crime decreased?
Another fact for you to chew on: Far greater atrocities have been committed by governments and their agents than by all other, non-government crime combined!
Keeping the government under control is way more important than lowering crime, if you look at the big picture. That's why the Constitution is all about controlling government and not about crime.
