We can certainly hope so. But if it turns out otherwise, I trust you'll agree with me that the perpetrator(s) need to be put away forever.
Yes, if they executed them in said fashion, they need to be punished according to the UCMJ.
If, as I suspect, they did no such thing -- they were either collateral damage, or the Jihadis are staging this -- then every American worthy of the name needs to come down on Murtha and the MSM like a hellfire missile.
