you'll find if you ask the police why they are there, they normally reply "to keep the peace"
No crime has been committed, they don't yet have the evidence to make it a crime (IE they cannot prove you have a tv)
theres lots of funny videos on youtube "how to deal with TV licence" should yeild good results in the search box
also you can legally own a tv and not need a licence,
IE for viewing DVD's, playing games consoles etc.
its as soon as you watch/record live broadcasts you "need" a "licence"
