The show cop's

I was just watching the famous reality show cop's and something occurred to me and that is these criminals on these cop's episodes are really dumb. I mean really dumb. Especially when the cops themselves interact with them. Personally, I think it's entertaining to watch how these criminals get caught red-handed doing something and then they try to say they didn't commit the crime that they just literally committed right in front of the police officer's face. I mean it always amazes me how they think the cop is stupid enough to deny what he just witnessed with his own eyes. But, of course, I think that's what make's the show so universally appealing- The stupid criminals the cops interact with on the show.
