Of course, opposition parties will make hay while the sun shines, gouging away at any Government embarrassment or misdemeanour. But the phrase "let he who is without sin cast the first stone" comes to mind.
In the meantime, 25 per cent of Kiwi children live in poverty according to the Children's Commissioner and we have sufficient social ills - health, housing, addictions - that we might need all Mr Liu's wealth to put them right.
So, hopefully, the grandstanding and chucking of brickbats will subside and those who seek to run the country - or continue to run it - will put the same effort into sorting out those issues that they put into parliamentary point-scoring.
Of course, policies to help those in need don't play as well in the media as high-ranking politicos having the rug pulled from under them.
The most worrying factor in the Williamson debacle is not his phone-call blunder, but Liu's $22,000 donation. You only give that kind of dosh away if you are seeking to buy favours.
All parties have their friendly donors - look at Kim Dotcom's generosity - and what that say is that rich people can get special treatment from a supposedly democratic government that ordinary people are denied.
That's one big pile of mud that needs to be cleaned up.
