The retired colonel who presided over the Quantico Marine brig during accused whistleblower Bradley Manning’s nine-month imprisonment there took the stand Tuesday during a pretrial hearing at Fort Meade, Maryland. Manning’s defense lawyers have complained he was kept in solitary confinement in a six-by-eight-foot cell and periodically forced to strip naked. During the hearing Tuesday, former Colonel Daniel Choike admitted Quantico was not adequately resourced for long-term confinement and said he had expressed concerns Manning should not be kept for longer than 90 days. Choike cited Manning’s “erratic behavior, poor judgment in the past and poor family relationships” as the reason Manning was placed on suicide watch and subjected to harsh treatment. Manning has been imprisoned for more than two years for allegedly leaking hundreds of thousands of documents to the website WikiLeaks.
