I'm not entirely sure I want the looters to go to prison. Sure, they lose their liberty but they get to hang with their mates, the kudos of being a con, time to work out at the prison gym and the chance to learn lots of other useful criminal tricks and contacts. And it alienates them even more from their communities.

I'd far rather they got some meaningful local community service which was enforced and might make them appreciate some hard work, see what local businesses and people are really like and try to engender some community spirit. After all, if you've spent all day painting a wall and some toerag then comes along and tags it, you might finally appreciate partly why people are so outraged about your actions.
