In Los Angeles after showing the judge video of elders standing in the dark at my entry waiting for me to come home at night and entering my garage as I pulled my vehicle in, I was granted permanent restraining orders against each elder individually and any "third party" related to the "congregation" and "organization of Jehovah's Witnesses"
Through video evidence once again, I was able to bring violation charges through the city attorney's office upon two separate individuals. While the penalty for them was light, 10 days community service, it sent a clear message and I have not had any issues for several years with local JWs. It also elevated the matter from civil to criminal and that seems to have put the elders in check.
It really depends on the lengths you want to go through to use the law in your location and how obstinate the JWs will be.
Be careful about using the "suicidal depression" tactic. If you have children or are going through a nasty divorce it will most certainly be used against you in court.
