Spet 2012 report from the U.S. Government Accountability Office to Congress found that in 2011, 48% of federal inmates were incarcerated for drugs.
The most severe crowding, puzzlingly, was in the highest security facilities: 55% are overcrowded. Perhaps that gang tag (discussed yesterday) has pushed this crowding.
Among unacceptable conditions cited are double and triple bunking, wait list for education and drug treatment programs, limited meaningful work opportunities, and increased staff/inmate ratios. These conditions contribute to inmate misconduct, which negatively affects the safety and security of staff and inmates. See the full report:
