Im not going to argue the constitutionality of stop and frisk, im not sure I even like it. People cant have their cake and eat it too. You cant expect security, if you dont want to allow the tools to be used.
Prevention is what saves lives, not arrests after the fact. People have to decide whether they want the tools used to enhance prevention or not. Thats what stop and frisk is about, prevention and I realize the problems that go along with it.
it would also prevent crime if the police were allowed to enter your home and search it, where do you draw the line...
