Even before it showed up in a secret police report, everybody in Bay Ridge knew that Mousa Ahmad's cafe was being watched.
Strangers loitered across the street from the cafe in this Brooklyn neighborhood. Quiet men would hang around for hours, listening to other customers. Once police raided the barber shop next door, searched through the shampoos and left. Customers started staying away for fear of ending up on a blacklist, and eventually Ahmad had to close the place.
But when asked if he would consider legal action against the police, Ahmad just shrugs.
