Sheriff Joe Arpaio, of Maricopa County, Arizona.
(From what I've seen, he's never met a camera he didn't like. First things that pop in my mind when I think of him:
~Tent City, green bologna, pink underwear, chain gangs.
~The controversial inmate deaths at his jails (i.e., one woman left out in a cage without shade, for hours, after she had been forgotten by the correction officers.
Another inmate, Pete Van Winkle, beat another inmate, Robert Cotton, in full view of jail surveillance cameras. The video is actually on the Internet, for anyone to see.
Another inmate, a woman, complained of abdominal pain for two days, begging to see a doctor, was refused & ignored, and died in her jail cell.
Yet another inmate, died while in one of those restraining chairs.... those are the deaths I remember off the top of my head.
~ Ask him why celebrities, such as Glen Campbell, seemingly receive special treatment while incarcerated. (Campbell, incarcerated after multiple DUIs, and even assaulting a police officer, was allowed to bring in his cell phone, guitar, and received all kinds of extra privileges).
~ Last but not least, ask him his views on illegal immigrants.
Arpaio is very controversial. He would be a very interesting guest, in my opinion.
