No one gets sent to prison because of TV licences.
Nobody ever gets sent to prison for not having a TV licence. It is not an imprisonable offence.
People occasionally get sent to prison for refusing to pay the court-ordered fine that they get for not having a TV licence, but that's a different thing all together.
Only if by different you mean the same.
Simple solution: Put all of their shite behind an id system and charge a fee for that. Don't monopolise fucking live tv as if it runs off the stored farts of Jimmy Saville.
And how about that time in the 80s when MPs went on primetime TV and ate cheeseburgers telling the public british beef was safe - knowing it wasn’t - protecting the small farms that skirted the safety precautions and were slaughtering sick animals and feeding people poison. Then thousands dropped dead of CJD a few years later.
How about that time the british media told the public to allow themselves to get infected by covid and encouraged them to gather? Whats the body count for that I wonder?
