Which ad hominem attack are you referring to BTW?
Howsabout this one:

Staines. A sensationalist blogger with a criminal past.

Yet he managed to destroy Peston's troublemaking allegation with irrefutable facts.

Tell me where I am in error.

As always when the left refuse to accept the message, they attack the messenger and when called out make a pathetic attempt to act the innocent.
By your post you would appear ignorant of the meaning of ad hominem

Yourconcernwould be better placed trying to undersyand the postion of the government faced with inadaquate testing gear in limited quantities and decideing whether to give priority:
1)to front line NHS workers
2)to patients
3)to the wider community.In order to introduce higher precision for modelling and hence forward planning.

You seem to expect black and white answers when the entire world is in the twilight zone of a pandemic. In the real world black and white is a bonus in many situations, outcomes from decisions are often uncertain.
