AFAIK the former prince Andrew was arrested in relation to national secrets he was giving to Epstein, not because of the pedo stuff.
Was it the bare minimum? Yeah, pretty much. But they aren’t even doing that in the US. The bar is extremely low yet the US is still managing to walk underneath it without even needing to crouch down.
Andy was arrested and immediately released. Trump was arrested and immediately released. What are the brits doing different?
