Lone Survivor' Marcus Luttrell Has to Restrain Himself On-Air When Asked This Question About Chris Kyle's Killer

Marcus Luttrell, a former Navy SEAL and author of “Lone Survivor,” was completely unfiltered on Wednesday night as he reacted to a Texas jury’s decision to unanimously convict Eddie Ray Routh for murdering legendary Navy SEAL sniper Chris Kyle and Chad Littlefield.

At one point, Luttrell had to restrain himself from answering a question about Routh on "national television."

Luttrell posted a chilling warning for Routh Tuesday on Facebook, writing, “To Eddie Ray Routh, you thought you had PTSD before .?? Wait till the boys in TDC Find out you killed a TX hero.”

“It’s not secret that usually I don’t have a filter,” Luttrell told Fox News when asked about the post. “What comes through my head is going to come out of my mouth. … I don’t know that he’s going to read that, but I’m sure someone will get it to him what’s about to go down when he gets where he’s going.”

He continued: “You’ve got a guy who, one was copping to something that wasn’t real. And two, shot a guy in the back, which is a cowardice act. It’s not going to bode well, we’ll just leave it at that.”

When asked about assertions that post-traumatic stress disorder may have contributed to the killings of Kyle and Littlefield, Luttrell said the claim is “garbage.”

“First of all, having PTSD is not a straight line to commit murder. It’s not a straight line to do anything breaking the law. Because if it is, basically you’re saying if I cop to having PTSD, I can go out and slap somebody around all I want and when the cops show up I can claim I am a veteran and I got PTSD — that’s not how that works.”

Finally, when asked about Routh’s non-reaction to his guilty verdict, Luttrell paused and then replied sternly, “We don’t need to get into it on national television.”
