It's easy for upper middle class white liberals to criticize some of these policing strategies, because they never had to live in the South Bronx or East Flatbush.
Yes, because I'm sure that people in the South Bronx strongly support stop and frisk 
You'd be surprised. When crime is out of control in your neighborhood, you tend to value public safety over legal technicalities. There is not a great relationship between cops and the residents of these neighborhoods, sure. But, most of them have not been stopped by police, yet they have seen the murder rate down 80-90% under Ray Kelly.
First of all, the idea that this is a "legal technicality" is ridiculously removed from people's actual experiences. This is about being able to trust the people who are supposed to be protecting you and being able to live without automatically being labeled a suspect because of the color of your skin. That's not a "technicality".

The wealthy white liberals who support[ed] Bloomberg are very much in favor of this practice, which is exactly why it has support in as liberal a city as NYC.
