why would inmates be behind the desk like that? >> while carswell restrains burden, deputies handcuff him and thank the inmate. >> tapped me on the back and told me good work. you all right, carswell? are you okay? >> the jail's medical unit treats deputy moon. he has a few bumps and scratches and is clearly shaken. douglas burden, who was in jail on allegations of drug violations and plead not guilty, is moved immediately to a confinement unit and locked away for 23 hours a day. he is charged with battery on detention facility staff. burden again pleads not guilty and is awaiting psychological evaluation. burden's reason for the attack isn't certain. >> there was some reports that earlier in the day moon had disciplined burden and that he corrected something he was doing and told him not to do it again. but that happens every day in jail.
