Some police officers aren't fond of that term. "We don't do speed traps," one says. "We do selective traffic enforcement." Yeah, Smokey, whatever. We know they love to lurk, and the lurkiest of all are Miami Shores's finest. Their quiet little village stands astride four major north-south arteries, giving the coppers there ample high-speed prey. A particularly rich hunting ground is Biscayne Boulevard, right where it curves northeast at NE 88th Street. The smooth asphalt and wider lanes here fairly scream to a Miami motorist's raging id, "Fifty! Do fifty!" Listen to your dark side and you'll likely run afoul of the black-and-gold Shores cruiser tucked away in the parking lot of the Hacienda Motel. On top of that, this past year the department instituted a zero-tolerance-for-speeding program called "Safe and Slow." Be afraid.
