BBC News: Police mocked for 'obvious' signs.

A police service has been criticised for using blindingly obvious messages in its campaign posters.  "Don't Commit Crime" is stated on one of Hertfordshire Constabulary's posters - "All fuel must be paid for" has been added on posters at petrol stations. Language watchdogs the Plain English Campaign said the notices were funny, but an insult to people's intelligence.

I like the Plain English Campaign.  They award the Crystal Mark for examples of plain, jargon-free english, Golden Bulls for gobbledygook, and Foot in Mouth awards for baffling comments by public figures.  The title of this post is a quote from MP Rhodri Morgan (First Minister of Wales), which won the Foot in Mouth award in 1998.

The campaign also offers several guides for writing in plain English and a free application, Drivel Defence, for inspecting websites for intelligible language.
