Ah, the casino. A place to lose your cares, throw caution to the wind -- and do it all under the cold, unblinking eye of a camera digitally recording your every move. In the three state-regulated casinos recently opened in Broward County, law-enforcement agents watch the casino floor with hundreds of cameras that can zoom in to reveal the smallest of details, down to the serial number on that USD 5 bill you just fed into the Wheel of Fortune slot machine. Private security forces do the same at the Seminole Hard Rock Casino near Hollywood.
