PAT TILLMAN KILLED BY FRIENDLY FIRE

This breaks my heart:

Pat Tillman, the former Arizona Cardinals football player, was probably killed by allied fire as he led his team of Army Rangers up a hill during a firefight in Afghanistan last month, the Army said Saturday.

Link here.

I know it doesn't change the fact of Tillman's bravery or willingness to sacrifice himself for his country, but it does somehow illustrate the whole nature of this CF, doesn't it?
