Death for shorts?

Update 10: Iraqi Athletes Killed for Wearing Shorts - Forbes.com

If this report is true, Muslim extremists are even more screwed up than I thought:

Last week, gunmen in Baghdad stopped a car carrying a Sunni Arab tennis coach and two of his Shiite players, asked them to step out and then shot them.

Extremists have been distributing leaflets warning people in the mostly Sunni neighborhoods of Saidiyah and Ghazaliyah not to wear shorts, police said.

I assume this is talking about males not wearing shorts. How exactly is wearing shorts an activity deserving death? I thought from previous posts I made about Saudi Arabia that the thing with women having to be covered from head to toe was based on the idea that men just couldn't control themselves if all those seductresses showed so much as square centimeter of flesh. But why are men's legs a moral danger?
