The "detector vans" are FUD, what they actually do is just assume that everyone has a TV and send them a letter. The TV licencing company (and it is a company, not a government organisation) is quite misleading in the way it practices, their inspectors cannot for example enter your property unless you let them in. And they can't force you to answer any questions. So there's no way for them to prove you're watching TV without a licence. All that said, personally I think the TV licence is awesome value for money, BBC TV and Radio programmes are generally of very high quality, and of course there are no adverts and there are very strict guidelines on impartiality etc
