This is a sad story all around. I don't know anything at all about Navy SEAL training but this sailor was struggling in the water and the instructors continued to push him which is part of the training but maybe in some areas you need not push so much. I cant say. I feel bad for the sailor, his colleagues and the instructors who may have been involved in this. The autopsy indicated several factors involved in his death but the ME basically called it a homicide.
