The King has made it very clear that he was entirely unhappy with Andrew's involvement for years, but had Andrew done the right thing and entirely disappeared from public life he might have retained a degree of protection.

He didn't and so he had everything stripped away which sent a very clear message to Government and the police that he was there for the taking.

It's not the King, it's the government, really. In any case, one of the reasons, if not the main reason, is that the scandal has unfolded very publicly so that covering it up is not an option as it might have been otherwise or previously.

It's striking that the specific offense, misconduct in a public office, is exactly what the supreme court recently decided a US president can never commit. In at least one concrete way our elected leaders are less accountable than their royalty.
