Risking understatement, I am buried alive inside Michigan's Marquette Maximum Security Prison. I am locked in a windowless cell measuring 10x8 feet, 24 hours per day. For one hour every other day, I am handcuffed, chained around the waist and allowed exercise and a shower in a small cage. I am not allowed to interact with others, or to participate in any educational, vocational, or employment programs. All meals are delivered to the cell. I have no access to a phone. And while I am permitted two, one hour non-contact visits per month -- always conducted through glass -- Marquette is 455 miles away from my hometown of Detroit. Opportunities to visit family and friends are rare.
