I agree with letting the childhood stuff go legally.
I live where there is deep corruption with city police as well as other officials. I had no dealings with police or legal system until a man I dated who was a therapist evidently was at least a participant in stalking me. I also had a dead animal, mail, unwanted phone calls, vandalism to my car, and I felt like a nuisance among other things. Police and legal officials made fun of mail of a sexual nature and I felt stared down at times. (some self conscious probably but also very real and humiliating to feel so unsafe that I had to report.) Im in US as well. Thing was, this therapist practiced 25 yrs in a small city of 25,000 population. He had dirt on everyone. I reported him to licensing board and he was disciplined, but I had to report confidentialities that he broke in telling me things about many people. My intent was not to harm but I had to provide evidence of unethical behavior. Since he is a sociopath, I suspect he was able to turn it around and make me appear like the nut. He quickly attached himself to a female therapist who he had spoke poorly of, even married her (still dogging around). He finds credible intellegent women to compensate and ride on their skirt tails to cover his sexual addiction. Police refused to take report for dead animal (officer was his client). Then officers harrassed my teen daughter. From this point on, anything that happens legally, I am blamed for. My reporting vandalism results in officers stating Im intoxicated when I am clearly not. (later discovered in report but not for yrs as I had no reason at time to pay for report)
Sorry to be blatently honest in my experience, but you cant beat city hall where I live. Small town and everyone talks. Knowing that has made me an ass at time-No, I have chose to be an ass with some at times. Sometimes unknowingly irritating I suppose with questions. None the less, it is clear that they would not help me if they saw me attacked. Even something such as vandalism, they act as if I would do it myself, I guess so I can pay the $1000 deductable. I would also say disappear, but that is a luxury that most of us dont have as you have said.
I would invest in any security cameras on your home and vehicle. Keep recording devices handy on your person. Remember that it does not matter if those people believe you-you know the truth. Dont let them push you to compromise your integrity. If the city police are the problem, have state or county on speed dial, and even talk to them in advance about the problem, often they are more understanding and educated. I think it will be your personal empowerment that is your greatest asset, though I lost mine through a long process. (This therapist has dirt on every cop, attorney, magistrate, etc). Even those not his clients, he has treated a neighbor, a maid, a secretary and knows the dirty little secrets. I cant be angry for them not protecting me, but to bully me , and they have, is just what people do here in the community that sufferes addiction, mental illness, poverty, obesity, etc at very high rates. Of course not all but way too many.
If you get something on video, dont take it to authorities, take it to media and explain why. Take it to civil attorney, of course after documenting all incidents as another poster said.
Sorry you are going through this.
