Two wrongs do not make a right.
It was wrong to let people into the Royal Albert Hall and I think the risk is too high (at the moment) to open up stadiums.
If it is too dangerous for me to see my grandchildren them mixing with hundreds of strangers can not be right.
Ifollow and patience I suggest.
STAY SAFE!
PS Going to the supermarket is essential going to sport is not.
I see your point, but in the test events that did take place recently as far as I know no cases were traced back to the event itself.
