Bruhns looks like a deranged psychopath in that pic.
And big deal- he got a tattoo at some scuzzy tattoo parlor. Anyone can get one, but only a deranged psychopath would get one to reinforce a psychotic delusion to “be all your schizophrenic delusion says you can be”.
I highly doubt this wierdo was part of any USMC combat unit, at best he was a supply clerk, stuffed out of the way somewhere after basic training when it was realized he was a deranged psychopath..
I think that he really was in a combat unit.
As to his actions on the night that the pictures were taken, you may want to listen here: http://www.youtube.com/watch?v=dbEC7ZuUUjg which is an audio of him loosing it, together with the photos.
