I would just echo the comments that have already been made.
I think offering an updated picture of an offender who's about to return to the community—perhaps it's only four years later, but perhaps it's 25 years later for some family members—is a really valuable thing for them. Many still do fear for their own safety. They want a little peace of mind to know what he looks like now. From my experience of going into prisons for parole hearings, I can tell you that they do often very much change from when they're arrested and sentenced. It's particularly valuable, I think, in domestic violence cases, where women are still fearful of their ex-spouse coming back to get them, to fulfill the promises that they made.
