The Civil War In Iraq

The civil war in Iraq continues despite Bush's surge escalation:

At least 45 dead after police officers go on killing spree in northern Iraqi town

BAGHDAD---- Off-duty Shiite policemen enraged by massive bombings in the northern town of Tal Afar went on a revenge spree against Sunni residents there on Wednesday, killing at least 45 men execution-style, police and hospital officials said.
The policemen began roaming the town's Sunni neighborhoods on foot early in the morning, shooting at Sunni residents and homes.

A senior hospital official in Tal Afar said at least 45 men between the ages of 15 and 60 were killed with a shot to the back of the head and four others were wounded. He spoke on condition of anonymity due to security concerns.

But Joe Lieberman still claims Iraq it is not in a civil war. My question is: Is Joe Lieberman a liar or unintelligent or both?
