p managing a sprawling urban correctional facility like san antonio's bexar county jail is a task full of challenges. from inmates acting up to dealing with gangs and an illicit tattoo trade, officers are constantly put to the test. >> these inmates in here do have time to study. they know almost everything about your job. they know exactly when you're coming. they know exactly what you're looking for. inmates that are actually doing the tattoo, they'll stop what they're doing, they'll put away everything. most of the time within 20 seconds. they have time to actually hide their tattoo rigs, their ink, they will hide it on top of the light fixture, under the stairs as well, in a toilet.
