NPR story about elderly sex offender prisoners

Yesterday's broadcast of NPR's "All Things Considered" included this fascinating long segment entitled "Sex Offenders Fill Geriatric Wards of U.S. Prisons."  Here is how the story begins:

In the geriatric ward of Pennsylvania's Laurel Highlands Prison, the floors are squeaky clean linoleum. The walls are painted in dull pastels. Dozens of inmates in hospital gowns line the hallways in wheelchairs, doing absolutely nothing.

Almost half of these men are sex offenders. They were once simply "dirty old men." Now, sex offenders in their 60s, 70s and 80s — like the men here — are a growing problem in the nation's prisons. Experts say it's the only crime that offenders are more likely to repeat with age. The result has been an explosion in the number of elderly men behind bars.
