Penal Colony

We are all mixed bags, and many of the people who are locked away to waste their lives in prison have talents or skills that could benefit society and maybe the world. So why not ship criminals off to a penal colony, like Georgia and Australia used to be, so they can duke it out with each other and maybe, down the line, become founding fathers? Of course, we have to find a barely-habitable planet first.

OMG, is Earth the penal colony for our galaxy?
