I do find some of it odd.
The point of lockdown and isolation is to not pass it on.
So, if I go out to walk my dog. we live in a town, in a quiet cul de sac. I can walk down my road, on to a footpath and then tp a nature reserve. I do pass a number of people, but can easily pass on the other side of the road, ie more than 10 m apart. Even on the footpath there is room for that.
In fact this morning, all the dog walkers I met were choosing to pass at a distance and wave, instead of stopping to chat. We can pass at a greater distance if necessary.
I just find it hard to understand why that wouldn't be allowed.
if we are not allowed to walk dogs, I forsee a huge rise in serious dog bite incidents in the home, as frustrated under- exercised dogs mix with frustrated house- bound kids.
and that is true of many things. Rise in suicide from those struggling with isolation.
Rise in domestic violence incidents,
Rise in child abuse (especially physical abuse) incidents
It is all very well to say everyone has obey lockdown, but lockdown is extreme due to the risk of increase in other things
