Its good to see some field reporters are doing it on air but are they wearing them all the time when they are not on air?
Some of those gatherings may still fall into being able to maintain distancing. But yes. Lead by example.
I don't see the reporter's efforts as good training. Rather fell good follow us! When noone else is at risk other than their cameraman. Which technically is workplace, so 1m.
As for off air. Probably about as much as the players in stand at the rugby.
If you wanted to educate a larger audience how not to. That was a great example
