do nice guys always have to finish last?

i live in an apartment building. my neighbor is a drug dealer. i reported it to the police. the police chief told the drug dealer that i ratted him out. the dealer then confronted me about it. my dilemma is what should i do legally about the cop telling the dealer about me? i was told by a local attorney to pack up and move to a new town but that just means the crooked police chief and the drug dealers can live by their own set of rules. the bad guys win. do nice guys always have to finish last?
