How do I file harassment against police officer who is a neighbor?

I have a police officer in town who is a neighbor. He uses private police information to get neighbors to harass me. He gossips and stalks me. He recruited other neighbors to engage in the same information. He has spread information regarding medication I was on and violated HIPAA laws. He gets neighbors to bully and ostracize me. He does not want a black living in his neighborhood and one who is single and dates interracially. He claims I am a blemish to community and gossips about prior work history. He has performed illegal background checks on me. He talks about it audibly outside my house to intimidate me. He recruits others to ostracize bully, harass me and recently I received proof from one neighbor he asked to join in and he forwarded the text. He has done this for years.
