Following the Bin Laden raid Devgru has hit the national media big-time, hence all the 'SEAL Team 6' stories. Anything happens it gets reported, when in the past it was never reported due to opsec (and anyways the media was never interested then). There are movies, magazine articles, books ....goodness, even a couple of former Devgru operators got in a spot of trouble over assisting a video game company make their game more realistic. By the way I am not hitting out at Devgru - simply saying they have become quite public in a way they weren't before, and some people in the special forces community have spoken against that publicity.
As an example, when was the last time you heard about CAG? The so called 'Delta Force' guys still maintain anonymity, and thus their could have been all sorts of mishaps that are simply never reported.
Anyways, Obama has nothing to do with this. This was an unfortunate incident that claimed the life of a brave American who was the closest thing to Superman this side of Krypton. May he rest in peace, and God bless others like him.
I don’t remember the source but I understand the death rate in training dropped when the army & marines went into actual combat duing Desert Storm.
