Crackdown on the Mahdi army or posturing?

"The first causality in war is the truth"
On Wednesday, Prime Minister Nouri al-Maliki said 400 fighters from the Mahdi Army army had been arrested over the past several weeks. Although, Yassin Majid, a senior al-Maliki adviser, denied earlier reports that dozens of senior militia leaders had been detained were incorrect.

In fact, US Occupation forces and the Iraqi army raided Um al-Maalef, a Shiite neighborhood in south Baghdad, on Tuesday and, detained every man who was able to carry weapons - about 400 people in all - nearly all who have been subsequently released. The Mahdi army did not respond under orders from Sayyed al-Sadr and no weapons were recovered. US troops did not enter civilian houses during the raid. No one was killed during this raid. Compare this with the raid in al Haifa street (a Sunnite stronghold) where over 50 were killed in one day.
