In the past; Colosseum was home to great public shows, most importantly Gladiatoral combats. Too bad what's left of it is a touristic sight. How about restoring it to its original state to be used as a public theatre where convicts are forced to fight each other? it'd be nostalgic. Imagine not having to feed rapists, terrorists and child molesters in prisons and instead of executing them in a dull way they could be used for public amusement.
