"According to figures from the Ministry of Human Rights, the number of Iraqis detained nationwide from the end of January until the end of March—a period that includes the first six weeks of the new Baghdad security plan—jumped by approximately 7,000 to 37,641. U.S. forces swept up 2,000 prisoners a month in March and April, almost twice the average from the second half of last year. Iraqi arrest numbers are roughly equivalent. Some of these detainees are falling into a kind of legal limbo, held for weeks without a hearing. Others are allegedly suffering even worse fates. The top U.S. commander in Iraq, Gen. David Petraeus, is worried enough that he issued an open letter to American advisers paired up with Iraqi units last week: "It is very important that we never turn a blind eye to abuses, thinking that what Iraqis do with their own detainees is 'Iraqi business'.""
