Im being harrassed. Any advice?

I have been experiancing a huge amount of harrassment by a neighbor. Its really got out of control. Most people would say "Just call the cops and report him." Im not much of a cop caller, I dont really put myslelf in situations where I need to get the police involved. Where Im from, we handle things on our own if its that big of an issue. However, it has gotten to the point a couple times where I would have called and reported him but thats actually what makes this promblem 100x worse, this man actually works for the local Sheriffs Department so Im afraid that would only make things worse. I live out in the country now, about 50 mins outside the St Louis County line, so they are not 100% LGBTQ friendly out here, dont get me wrong most of them are just fine and in the 12 years Ive lived here, this is the first encounter I have had tho, I have heard some stories. The next part is without a doubt an issue if I decided to report him. I have no idea who this guy is, what he looks likeis or even where he lives exactly. It all began as a fluke really, one day i just happen to mute my TV to answer my phone and when I did I could hear a man outside yelling. it was not very loud - like he was far away but I could hear what he was saying very clearly. it was the weirdest thing I had ever experianced, I literally thought i was going crazy the first few times it happened but sure enough one day a Police Cruiser drove passed my house and the siren came on, it was a very loud siren and it shut off right after it passed my driveway and where i live, there has never been a cop on my street let alone one that drives by doing this. One night we was literally yelling "We dont want you here!!!! You need to move!!!" Ill be sitting outside or working in my yard and all the sudden in the distance you can here this man yelling. Hes been promising for like 3 months that if i find out who he is, he will "ruin my life". Im at the point where im willing to take the chance in order to get him to stop doing what hes been doing. Hes gone as far as hacking my phone and shutting down apps. If it has anything to do with LGBTQ he goes into a tail spin.

I litterally just heard him yell "That's it!!!! I TOLD YOU TO STOP!!!"

I am sitting in a basement, in the far corner where there is no windows or doors, I cant for the life of me figure out how is sees my every move but its really very creepy, totally immature and 100% uncalled for. I have never once bothered this man, sad an ill word about him or done anything that would affect him in any way shape or form. Ive yelled back a couple times to "knock on my front door like a real man if you have a problem" but he chooses to keep his distance. I would hope that since he is a police officer, he knows he is doing something highly illegal which i can only assume is the reason why he wont do any of this to my face or where I am able to put a face with the voice. If i knew where he lived, I would have knocked on his door myself but i havent gone digging because this person seems like a loose cannon and he is probably a very shady person and quite honestly, i dont want to be the one that finds out what a crooked cop can really do to "ruin my life" but he sounds well prepared and experianced. I just thought I could get some good feedback from people here before having to do some as drastic as relocating just to get away from him. I would love to hear anyones advice or opinion as to what i should do.

Thanks much!
