People are tested before discharge from hospital and before going in. No country has got everything right with this pandemic. Are you suggesting a different political party would have improved the death toll.  If so who? 
And yes making horses jump over barriers with a human on their back is cruel.  I'm sure the horse would rather run freely.

All these old people the snp put to their deaths. Now that is cruel don't you think ?

And horses love to race.
