The Lip TV
Eddie Ray Routh, the confessed killer of “American Sniper” Chris Kyle and another man (Chad Littlefield), is discussed by The Lip TV. They look at his confession and his defense of PTSD-based insanity, as the prosecution has rested in his trial. The Lip TV talks to Jack Downing and Mike Cavalluzzi about the murder.

OK, Fine. 
Didn’t watch the video (just too long) and maybe they covered this but based on what I’ve read it offends me that he is claiming PTSD … http://warfighternews.com/2015/02/10/eddie-ray-routh-the-untold-story/
Sounds to me like he has always been a little whacked, but also that he fundamentally knew what it is he was doing that day.
