For a couple of centuries, the country operated on the premise that vagrancy laws and other statutes hostile to the criminal element were not "unreasonable". Again, was the country really one vast gulag before the 1960's? I seem to recall an era when people left their homes and their vehicles unlocked.
We're not talking about vagrants. We're talking about people going about their daily business and getting stopped and felt up by the filthy pervs in blue. NYPD might as well be TSA scum.
