Certified they may be. I doubt that the ‘virus’ cares about certification.
Like that old joke:
A rather cocky U.S. Department of Agriculture representative stopped at a farm and talked with an old farmer in New Hampshire.
He told the farmer, ‘I need to inspect your farm.
‘ The old farmer said, ‘OK, but don’t go in that field right over yonder.
‘ The Agriculture representative said, ‘Mister, I have the authority of the United States Government with me.
See this badge? This badge means I am allowed to go WHEREVER I WISH on any agricultural land.
No questions asked or answered. Have I made myself clear? Do you understand?
‘ The farmer nodded politely and went about his farm chores.
Half an hour later, the farmer heard loud screams and saw the Agriculture Rep running for the fence and close behind was the farmer’s huge-horned prize bull.
The bull was gaining on the Agriculture Rep with every step.
The Rep was clearly terrified, so the farmer immediately threw down his tools, ran to the fence and shouted out:
‘Your badge! Your badge! Show him your badge!’
