I Feel Like This Is Kind Of Degrading...

For some reason I look more at the guy in the upper right, and he almost seems to be in a cocky "holding the edges of his jacket" pose. Now that you bring it to my attention everyone else does look like they're getting perved on.

Yeah it is.

;)

That's hilarious. Any idea why they had to hold their hands like that?

I found this: The inclusion of hands in the mug shots provided an additional point of identification for the police: missing fingers, scars, and the general shape and condition of the prisoner’s hands could all help in the identification of a suspect.

I'm late, and I see DashHopes answered your question.
