The vertical portions of each stairwell, located between each step, have been made see-through to increase visibility. When outside, prisoners congregate in small groups, in separate recreation yards attached to each housing unit. We have systems that have been implemented that manage the inmates, that make the prison safer. That's a big reason why you can have such large numbers, because you don't have 1,500 inmates standing around the yard at the same time.
