The US media also just likes to try to protect the emotions of the consumer. Some of the articles I've read of scuba diving accidents in the Mexican press are very NSFW by contrast and they'll just show you a dead guy in a wetsuit. In fact a lot of lifeleak content comes from new stories in other countries. Most Americans don't want to think about death and their own mortality or anyone else's mortality and want NSFW warnings splashed over anything remotely unsettling.
