It's a sporting event, the fact that you try to compare it with camera crews arriving to document car crashes, or other current events, pretty much says it all. Apart from you speculating, there's little to back up your claim in regards to sporting events and camera crews. In terms of photographers, yes, but they're well aware that there's no risk of it going straight out for the world to see.
"Oy Steve, if a player is about to die, make sure you zoom in to get the close ups of his face as we might need it during broadcasting. Chris, see if you can find his wife on the pitch".
Sounds legit.
Zooming in on the faces of the Danish players that are standing in a circle around Eriksen, to film every reaction. Zooming in on his wife on the pitch. It takes a special type of cnut to do so. So yeah, i easily blame every cnut behind the camera, fully aware of the situation and that the player might already be dead. The full responsibility lies with the cnuts at UEFA that are in charge of the broadcast, for not switching to a completely different camera, though it doesn't absolve the people behind the camera for actively zooming in and out of the situation looking for content, nor does it absolve companies around the world for not having the common sense to instantly cut when they noticed UEFA were broadcasting everything.
