If you are a molestation victim of william hamilton ayres, alleged child psychiatrist, whether it was recent, or a long time ago, and you have not talked to the San Mateo police department, or the District Attorney's office, it's still not too late; in fact, there are three extra weeks, thanks to Doron Weinberg's trademark lack of preparedness.
If you're concerned about anonymity, at least as far as public release of your name is concerned, call the PD or DA, and they will be able to clarify for you what the situation will be. You won't be forced to testify if you just call and ask about it. Ask them every question you can think of. Get it comfortable with their answers, THEN call them back and make a statement if you want.
I'm not saying that it will be a walk in the park. Honestly, it hasn't been for me, and probably will continue to stink. BUT I don't think it stinks any more than it would have anyway, and you might be able to do some good, and that would make it stink a whole lot less... and, you may not have as much to fear as you think
Give Rick Decker a call at the San Mateo police department. If you talk to him, I think you'll find him to be reasonable and patient. Ask him about the things that you're afraid of, related to coming forward. Discuss what options they'll have for you. Don't feel obligated to make a decision, but DO get the run-down from Detective Decker, and then give it some thought. Something that took a long time for me to become clear about was that it would look pretty bad for them to have to drag unwilling victims to the stand to testify. If you call them, and ask about what will happen if you come forward, and then decide not to, they're NOT going to trace your call and send the SWAT team to come and get you. It took a long time for me to get that through my head.
