Aviva has been following the suggestions avidly. She was very excited at Mr. Moles's suggestion (not least that it was from him), but her interest flagged while reading the wikipedia links, since the various projects seemed mostly engaged in convincing everyone that prisons were a bad idea, a project she greeted with perhaps merited suspicion as to its efficacy, as opposed to just going and knocking down prisons.
She wanted to wait and see if anyone had a suggestion to that effect, but after a little more discussion about what that would entail (i.e. there are police officers whose job would be to shoot at people trying to bulldoze the prisons, and that ultimately this sort of thing can start a war), she began to cool on the idea. "Well, I don't want to start a war," she said.
Therefore I believe the Innocence Project is the current front-runner.
