You got me thinking - it would be 'cruel&unusual' and invoke flashbacks to barbaric times, but a '3-strikes' policy that would put a permenent, visible brand "i'm a thief" or "i'm a con-man" would probably deter opportunities future crimes.
It's not humane and it restricts liberty - but it's more humane and less liberty-restricting than the corrent "solution" of permanent imprisonment.
Are you kidding me? What do you want to do instead, cut his hand off?
The sheer lack of imagination and knowledge you exhibit is astonishing. If I don't think it's smart to imprison him, I must want to cut his hand off? Let me guess; you're a US citizen and you don't travel much, so all you've ever seen regarding prison policy is identical US politicians posturing over who can be more "tough on crime"?
