well, I dunno, gromit, the actual criminality exposed was pretty slight - a couple of people claiming on mortgages they didn't have? (Apologies if I've forgotten other examples.) The rest included some ethical spivvishness, much sitcom hilarity about duck islands, and a fair amount of non-newsy stuff about grocery bills that were perfectly in order.
I'd have had no problems with the Telegraph printing just the criminal stuff. But printing everyone's expenses when they were due to be published anyway looks to me like the Telegraph just wanted a scoop - they paid so they could get in first. If Parliament's own publication of the expenses had been equally transparent, the Telegraph would have had great difficulty saying they'd done anything very much in the public interest. Fortunately for them, MPs' own mania for secrecy retrospectively justified the newspaper, which is when I agreed it had done the right thing after all. But I don't believe it was clear-cut at the time.
