Leaving aside the fact the TV Licence is in fact a tax, the problem is that has been out-sourced to Crapita, who have a track record of being shhhhh... ameful and trousering large amounts for doing so.
They work on the assumption that everyone watches television and bombard every address without a licence with risible threatening letters: envelopes trimmed in red and carrying, on the outside, dire warnings of the consequences of WATCHING TELEVISION WITHOUT A LICENCE!!!!!!
In order to convince them that you are not undermining the integrity of the free world, you must (at your own expense) contact them to plead your innocence and then submit to an inspection to confirm that you are not a liar.
Watching programmes broadcast in realtime is a criminal offence (farcical in itself); the criminal law places the burden of proof on the accuser yet Crapita blithely ride roughshod over this.
Do the Police require that I prove I am not a driving illegally on the basis that I don't have a driving licence?
What if I was to send the Chairman of Crapita a letter requiring him to prove that he wasn't guilty of sex crimes, with the penalties for such offences emblazoned all over the envelope?
To the barricades!
