Any person be it male or female that steps out onto public areas and dresses in a dress/bikini/sexy outfit is putting themselves out there for anyone else who in the same public space to see. If they do not want that to happen, put on some clothes or do not go out in public.
Also, you threatened this individual. He could have pressed charges, and then you would be responsible, no ifs, ands, or but(t)s. He was not breaking any laws. Learn to curb your temper and do not worry about what others are doing. If you do not want public images of yourself or wife while scantily clothed, do not go out in public dressed so.
I also agree with an earlier statement - he deleted all the images and went back to his room and then recovered them all.
If you are still having difficulty with this, think of it as a form of flattery.
