Paul tweeted, "Chris Kyle's death seems to confirm that "he who lives by the sword dies by the sword." Treating PTSD at a firing range doesn't make sense."
As some on Twitter pointed out, Paul is wrong about PTSD treatments. One of the most effective treatments, called Prolonged Exposure Therapy, involves exposing PTSD sufferers to their trauma's triggers.
Others on Twitter simply responded with anger, calling Paul's tweet "disgusting" and "disrespectful." Another user speculated that the tweet didn't come from Paul at all, but from a shortly-to-be-fired intern.
