is there a good lawyer in New Jersey?

My son was suspended from college for allegely doing a drug transaction. After three months of investigation they found no evidence to sustantiate their allegation, so they drop the drug charged, and instead charged him with unruly conduct, and creating an hostile environment just to justify suspending him from college. I need a lawyer because I believe that upon investigation evidence will show that my son was more than cooperative, because he was not under any obligation to sign anything to allow the police to body search him, or the car because he was not under arrest for anything at that time, but he knew he had nothing to hide. Ironically, a day before court, I recieved a cerified letter from the college with all the allegations on it, and miraclously the drug allegation was missing, he went to court and the police drug charge was thrown out too, but no one mentioned as to why they arrested him in the first place with no evidence, from the school or the police officer
