The takeover began after the last election in December when Sadr's political faction was given control of the Ministry of Health. The U.S. military has documented how Sadr's Mahdi Army has turned morgues and hospitals into places where death squads operate freely.
Hospitals have become command and control centers for the Mahdi Army militia. Sunni patients are being murdered; some are dragged from their beds. The militia is keeping hostages inside some hospitals, where they are tortured and executed. They're using ambulances to transport hostages and illegal weapons, and even to help their fighters escape from U.S. forces.
A hospital worker says Mahdi Army spies are everywhere, and would only talk with both face and voice masked. "A man was bringing his murdered brother to the morgue. They asked him if he knew who the killers were and he said ‘yes.’ They shot him right there," she says. More than 80 percent of the original doctors and staff where she works are gone, replaced by Shia supporters of the Mahdi Army.
"It's going to get worse because there is no control and no accountability," the hospital worker adds. "No one can stop them. They are terrified... No one will be safe. There will be destruction. Complete destruction is what we are watching with our own eyes and it's getting worse."

Bush didn't kill Sadr in August 2004 because the WH decided it was too close to the election to take the chance so they let a monster every bit as evil as Zarqawi, but smarter and more patient go free.
