I was racially profiled and accused falsly of stealing?

i went into a store and was followed the whole while i was in there and after i purchased what i wanted the employee wrote my tag number down as i was leaving .i stopped and ask her why was sheb doing that she then went on about she can do what she want i then asked to speak to a mgr she said she was the mgr .iaked her why was she following me all over the store she said cause all black men steal i have 2 wittness that heard her then the po was called out cause she said i stole something i and my vehicle was searched and nothing i did not pay for was in my possession. i have been greatly damaged by this because several people that work in stores in the area saw me being detained by the police and some heard her say i stole something so when i go in there store they began to follow me can i sue for slander discrimination and racial profiling.
