From the House to the fancy house to the big house?

It's amazing to watch the scandal unfolding in Britain over MPs' ridiculous housing allowance claims. The Daily Telegraph has been all over it and it's the usual picture of a system ripe for fiddling by politicians with a runaway sense of self-important entitlement. But they're getting caught. Revelation after revelation spills out, some heads have already rolled a short distance at least and much more is to come, both political disgrace and possibly criminal prosecution. Why are the British so good at rooting these things out? Surely there are some lessons we can learn, not about preventing scandal perhaps, but about exposing and punishing it.
