The "Safety First" freepers would never admit they are just Bloomberg's stooges. They will claim to both fight against Bloomberg's infringment but at the same allow special cases like Watertown because it was (1) so important to catch this one terrorist or (2) so inconsequential to search a few hundred houses and/or (3) we didn't hear any reports of resistance so it's ok.
Bloomberg has a solid history of ignoring the 4th which is the main reason that NYC's murder totals were less than Chicago (where they don't stop and frisk). There's ample evidence from Japan that stop and frisk (and no 2nd, 4th, or 5th) works. That's probably where he wants us to end up.
To those that say the didn't hear of any reports of resistance let me ask you in this picture from one of those searchs who do you think at that moment these people are more affraid of, the terrorist on the lose or the police with machine guns at their door?
