The U.S. military grounded all daytime operations by CH-47 Chinook (search) helicopters Monday after Iraqi insurgents downed one the day before, killing 16 soldiers and wounding 20 others.

"Any time you have an attack on a — successful attack on a helicopter, you have to say it is a tragic day for those people who were killed and wounded. We know that. But there are going to be days like that," Defense Secretary Donald Rumsfeld told Fox News Sunday.

Will Sunday's attack weaken the resolve of the Bush administration to stay the course in Iraq? DaySide investigates with retired U.S. Marine Corps. Lt. Col. Bill Cowan and retired U.S. Army Command Sergeant Major Eric Haney, author of Inside Delta Force.

Plus, how soon can the $87 billion request translate into improvements on the ground in Iraq? We’ll get reaction from Capitol Hill from Reps. Max Burns, R-Ga., and Vic Snyder, D-Ark.

And, we'll examine the role that DNA (search) evidence plays in the Laci Peterson murder trial with Mark Fuhrman, former LAPD detective; Jim Hammer, San Francisco prosecutor, and David Wise, criminal defense attorney.
