Yes, it's always seemed really bizarre to me that anyone would be locked in a cage unless they were a physical danger.

Now there's talk of locking up people for sharing files! Insane. If you believe that file sharing harms the economy (I'm pro-copyright to an extent) then fine the people, garnish their wages, watever. Locked in prison and chance of having a normal career ruined forever? What could be more cruel and unusual?
