"AT JUST 5 FEET TALL, Christopher Carroll could barely see out of the two narrow window slats of his cell door in San Diego’s Central Jail, where he ended up on June 14, 2014, for disorderly conduct and being drunk in public.

Four days after his arrest, Carroll committed suicide. Because of his small stature and age — he was 51 — he’d been placed in protective custody, a classification reserved for inmates deemed too vulnerable to be housed in the jail’s general population. According to the medical examiner’s report, he was also classified as “Keep Separate All,” a status that further isolated him, because during a previous jail stay, he didn’t get along with other inmates."
