I think this is a misreading of the situation. He’s being arrested because of recently uncovered evidence that he committed a crime. We can all form our own opinions on whether or not Andrew committed rape and/or sexual abuse (without too much difficulty, I assume), but this crime looks like it ought to be a lot easier to prosecute.

It's easy for the royal family to say they didn't know he sent an email. It's hard for them to say they didn't know about the girls, due to their security. This way only andrew goes down.

I think this is a very implausible take for two reasons.

First, the King doesn't have that kind of power over the justice system in the UK. He cannot choose when, whether or why Andrew is arrested.

Second, Andrew's arrest is a negative news story for the royal family, not a positive one. Their ideal scenario would have been one where the Andrew/Epstein story gradually dropped out of the news cycle following the stripping of Andrew's royal titles. This arrest, and likely subsequent trial, are just going to keep it in the news for months or years to come.
