As far as feeding anything to the pigs, I am making no firm conclusions about this case until the arrested man is convicted or exonerated. Seems like there was a lot of confusion at the crime scene, so much confusion that the Army arrested two people and later released them. The Army also stated for hours that the alleged perp was dead when he really was wounded. I am not disparaging the Army; it was indeed a choatic situation and it is likely that they have an explanation for all this. I am not assuming that the arrested man is either gulity or innocent until everything gets hashed out in court.
As for the 5.7 round, I am still of the opinion that the jury is still out on that round. It has been on the market for just a few years and there probably have not been enough documented shootings to come to any firm conclusions about it. It might be either a great man-stopper that slices through ballistic vests like a hot knife through butter or a weak .22 magnum equivalent that can't kill a squirrel with one shot. Speculation is fun and even productive in its way, but the proof of the pudding is in the eating.
One thing that surprised me was that Army bases depend on local law enforcement for SWAT services, at least at Ft. Hood. I always, perhaps foolishly, assumed that the Military Police would handle such situations.
