I am aware. It’s why they apologised because it’s footage they pay to get but don’t really control. When NBC showed the London Olympics they don’t actually film the event, they are BBC pictures they talk over.
There are cultural variations on these things, maybe Brits are a little squeamish compared to the French but if you go to India they report news of road traffic accidents with pictures of the dead bodies. Almost all sports hold some inherent dangers, I have seen that shin split in soccer and an Australian cricketer died a year or so back when a ball hit him due to an ill fitted helmet. I personally don’t watch sport for that, even contact ones with violent exchanges like rugby or American football.
You can’t ignore it happened, you don’t need to replay it 6 times.
