Excellent decision! Lots of precedences for this.
Which precedents are you thinking of?
During WWII, I believe that up until Tarawa that we didn't allow war correspondents to freely publish pictures of the dead, but I believe that from Tarawa onward that we allowed such pictures of dead soldiers.
Otherwise, I cannot think of any such restriction on the press, but the history of journalistic photography is not a part of history that I spend a lot of time on, so perhaps such restrictions were more common than I thought?
Poor decision unless we want to hear arguments over the true death count for the next hundred years.
