I need to find a law firm that handles discrimination in a retail store from a consumer's point of view

Yesterday in BJ's wholesale store in Edison New Jersey. I was stopped by 3 Edison police officers as I was exiting the store. They said the manager has a few questions for me. The store manager approached me and asked me to I take anything from the razor aisle. I said no why would I spend $50 in your store to steal $4 item. She said we have you on camera taking something from that aisle. So the police officer told me to step back in the store so they can check me. We stayed right there near the exit so everyone can see. We did not go to a private room to proceed with the search. I emptied out my pockets right there while the officer was patting me down. Of course they found nothing. The officer asked for my license and social security number. After they ran their checks they came over and the store manager handed me my license and apologized. She said they made a mistake. That I fit the description of another person that was stealing from the store and they weren't able to catch.
