Mathison v. U.S., 2015 WL 4296867 (7/16/15) (Col.) (unpb'd) - Mr. Mathison could not obtain relief for hearing loss he suffered soon after the Florence prison's public address system volume increased. The cause of the hearing loss was not plainly identifiable by a layperson. So he could not prove causation without an expert, which he didn't have. The 10th does not make any suggestions as to how an indigent prisoner like Mr. Mathison could possibly obtain an expert.
