Brisbon is now held at the Tamms Correctional Center, a "super-max" facility that houses more than two hundred and fifty men culled from an Illinois prison population of almost forty-five thousand. Generally speaking, Tamms inmates are either gang leaders or men with intractable discipline problems. I wanted to visit Tamms, hoping that it would tell me whether it is possible to incapacitate people like Brisbon, who are clearly prone to murder again if given the opportunity.
