The reason I contacted the police was that I wanted to delegate taking care of this to professionals. I'm not a psychologist and what I think might be a reasonable approach to helping out in such a situation actually might or might not be. (People seem to have very different approaches here from "I feel you bro" through "Hey it's not that bad" to "You can be really proud of x, y and z" and up to "C'mon, stop whining!" and even "It's actually your fault")
I'm very glad to see that this seems to have been the right decision. I wasn't too confident about it at first, b/c police really didn't leave a professional impression. When I read that post I was at work and my wife and kid were at home. They were quite shocked (and the neighbors probably somewhat "excited") that KriPo showed up at our place. Turned out, I was also right not to trust their research capabilities. I literally[1] stalked the sh*t out of you and sent them a good dozen of profiles together with your name, (work) phone number and address and the letter to your ex, her profiles &c. That may sound creepy but I actually really wanted to make sure they have all the information they need to reach out to you as fast as possible (I expected it to take minutes, not a week). Turns out doing so was both right and wrong: They really seemed not to be skilled investigators, but to the extent that some days (!) later they called me and told me they couldn't open the links.
So after that I really wasn't that full of confidence what concerns the police, so until I saw your HN submission in May I always thought about calling you but didn't really know how you'd react.
