DALLAS -- Mark Halstead remembers the last time he was outside.
The 17-year-old, being held at Dallas’ Henry Wade Juvenile Justice Center while waiting for his reckless driving case to be resolved, was allowed to walk outside one day in February with other kids to visit a mobile dentist. As they waited for their dental exams, he tried to get a glimpse of what was around the beige brick building.
Mark could hear fast cars. He was near a highway. He could smell sugary confections from a nearby candy factory waft through the air. He felt the sun on his face, relishing the heat and warmth.
