I was once asked to look at a portfolio of pencil drawings by an ex-prisoner; they were trite, unaccomplished, cliched, clumsy and painful to look at. They were without a scintilla of merit. When I said so than man\’s astonished representative said \”But the prison art visitor said he has a rare talent\”. \”What was he in for?\” I asked. \”GBH\”. \”Well,\” I suggested, \”he would say that, wouldn\’t he?\”.
