Doris, regarding the latter part of your post - I do not blame the woman in the least. I believe a good rule is - we live in a civilized country, and whenever we suspect something, we should call the police.
From my own experience. Back in 1998 (or so), I was working evenings at a "Pea in the Pod" (expensive maternity clothing) in the Atrium, a very upscale mall in Boston area. One evening, I was alone in the store, with just a customer (about 7 months pregnant) in the dressing room. A guy came in. He was Hispanic, and just didn't look like he belonged. My alarm bells went off, but I told myself it would be racist to call the security as I probably wouldn't feel that way if he were white. Well, too bad I ignored the alarm bells, because he ended up robbing the store at gun point. There wasn't much in the case register (just the standard $200, nobody paid cash there anyway), but the experience was terrifying; you can imagine what it was like for my customer!
Off topic, but the story did have a continuation. I tried to help the police with the composite sketch, but, hard as I tried, I just couldn't (it's not nearly as easy as they make it look on Law & Order!). Then, a few weeks later, the head of security came in and told me they caught the guy as he was robbing a Victoria's Secret. Then, though, he did something really bad - he showed me the picture of the suspect! A few days later, when police came in to show in a lineup of pictures, I just couldn't be certain if what I remembered was from the face I remembered from the robbery, or from what the idiot from security showed me! They plead the guy out, and the robbery of our store wasn't no the list of charges... Even though it probably wouldn't have added all that much to his time, it still left me very angry...
