On Freemont Street in Vegas there’s around 50 undercover officers on duty at any one time and you’ll lose money trying to guess who they are. They work the crowd of people walking up and down the street. When the light show starts is when they really keep an eye out for purse snatchers and pick pockets and they remove then with the efficiency of a special ops team, quick and quiet. New Orleans needs to do the same thing.
BTW, I was watching an episode of 'The First 48' and one of the detectives who showed up on the scene was unshaved and had an outfit on that made him look like a tow truck driver. He was NOPD all the way.
