I really loved getting to visit Alcatraz a few years back. I hadn't known about the Occupation, and that was one of the surprise highlights of visiting.
It's a hauntingly beautiful place now as a wildlife sanctuary, and it felt empowering to see a place used for cruelty returned to a place of peace and knowledge.
I'd hate to know anyone who would prefer it to be in it's former state again. That would probably make them pretty despicable...
