I thought I heard that the ban on news crews filming coffins was out of respect for the families. If all the families whose children were in those coffins wanted the news crew there, then it would seem appropriate.
If this was done at the request of ALL the families involved then it certainly seems the right thing to do, Pentagon policy be damned.
The LOOOOISIANAH NA'NAL GOORD isn't really accountable to the Pentagon. They are accountable to the State Adjutant General, their governor and the people of Louisiana.
