Racial Profiling

You stated that the "other individual" called the police.  It might be a situation where the person who called the police told them exactly what you were wearing and looked like (which could include your race), so that is why they made the arrest.  A very simplistic answer as to what is racial profiling is more of a situation where the police stop you and question you because they are "looking" for someone and you might happen to be the same race, or you might be stopped and frisked because of your race.  The way you asked the question would leave me to believe that they had a witness (or alleged victim) who described what you were wearing and who you were.   Sometimes the police really do not ask too many questions, if there is plenty of other evidence that would support probable cause that you may have committed a crime.  As for reading you your rights, that generally only applies to whether or not you said anything that could be used against you while you were being questioned (the right to remain silent).  The court during your initial appearance will inform you of your right to hire counsel or have counsel appointed if you cannot afford an attorney.
