This whole thing is getting curiouser and curiouser, BUT, when I saw that this article is an ABC NEWS source..
Well, we know how careful they are with facts, don't we??
the guy is NOT an eyewitness to the shootings....unless he lied to momma:
"Lance Cpl. Briones told his mother he saw the bodies of 23 dead Iraqis.
Susie Briones got a panicked call that day from her son, who said he did not see the shootings but was told by his supervisors to go into the houses and remove the bodies"
