FORT LAUDERDALE— Tania Ouaknine is convinced the police are watching her. She's not paranoid — it says as much on the red sign painted along the side on the hulking armored truck that's been parked in front of her eight-room Parisian Motel for several days. "Warning: You are under video surveillance," reads the bold message on the side of the truck. From the front bumper of the menacing vehicle, another sign taunts: "Whatcha gonna do when we come for you?"
