I can't help but wonder how many of us would approach a woman who was sunbathing topless, but not approach the same woman if she was sunbathing with her top on.
Whereas I totally agree that this was entrapment in the worst way, I question Robin's judgment anyway. "Hey, a topless woman! I think I'll go talk to her and see if I can get anywhere!"
How many of you do that, or would think of doing that? Why not simply let a woman sunbathe in peace, topless or not?
