Abu Ghraib. Originally, Saddam Hussein used it to house political prisoners and commit acts of torture.
After the U.S. invaded Iraq, the Americans used it for the exact same purpose; this time in the name of "freedom". It was only after pictures of detainee abuse by American troops surfaced that it was shut down.
Now the prison is open again, back in Iraqi hands. Same old story, only this time it's being renovated to hold five times as many prisoners as it held during Saddam's rule. Guess what? Some people are pissed.
