The msm says that this action was initiated by an ied, with no hint that terrorists actually set it off, let alone planted it. They make no mention that any of the "civilins" were in fact terrorists using the civilians as willing or unwilling shields.
You're dead right. "Civilians" planted the ied. A "civilian" set it off--probably at the signal of another "civilian". "Civilians" watched it go off and fired on the Marines. Did the "civilians" include women and children? That seems to be the mussie way.
