I am very grateful to all who responded to my post about my experience on Thursday. After a lot of thought, I decided to report it to the police, today! My wife has pretty decent Spanish, so the offer of help to go with me, although very kind, wont' be needed.
It is hard to get past the "don't be a tattletail" admonition we all were bombarded with as kids. That's why I was hesitant. But I believe it's the right thing to do now. If instead of me, that had been a little kid, heavens knoww what would have been the result. Thanks again evereyone.
