It's a lovely song.I wonder if Ms. Baez ever considered the remote possibility that some - a very few - of the people in the prisons just might have behaved in a way that makes it unsafe to allow them to remain at liberty. Of course, we could execute them all, but I have a feeling that she'd object to that too.
Granted, prisons don't work worth a damn in terms of turning people's lives around. But at least while the people in them are in them, they aren't murdering or raping or robbing.
Of course, the ones who are in for essentially victimless drug "crimes" are a different issue...but some of them really are dangerous.
