Back in 1994 a man was killed outside UMIST for fly posting on somebody else’s patch. (I was working in the Union at the time, and was- uncharacteristically- the first person in the morning after. I had to field a call from the Times asking if I thought the death was drug related. One of the inspirations for Another Education.) Somehow, I don’t think the threat of fines and a campaign by Keep Britain Tidy is likely to put people off.
