The complicating factor is that the man involved had been an extremely highly regarded activist on behalf of gay rights.

"an influential lobbyist who advised Scottish parliamentarians on youth policy, he rose to the height of his profession and was invited to receptions where he met the Queen and Tony Blair" and "the former chief executive of LGBT (Lesbian Gay Bisexual Trans-Sexual) Youth Scotland and a former president of Heriot-Watt University Students Association" ( Times Online)

That makes it a particularly shocking case, analogous in some ways to cases where other people in positions of trust have been found to have sexually abused children. It shouldn't be taken as suggesting that all gay men are pedophiles any more than all priests or all nursery assistants. But it is a reminder that respectability is no guarantee of anything.
