Andrew and Tristan Tate were arrested in Miami on a UK extradition request, a major turn for the influencer brothers who have long claimed the system is out to destroy them.

• US Marshals detained both brothers in Miami on Saturday after the UK sought extradition on dozens of charges, including rape and sex trafficking.
• The UK's prosecutors filed 42 charges against Andrew and 17 against Tristan, tied to seven alleged victims.
• The arrest was calm and orderly — the US is simply honoring an extradition treaty, while the UK is driving the case.
• Their lawyer says they are innocent and will walk free, calling it Britain's political dirty work.
• Their dual UK citizenship is what exposes them to extradition, even as American citizens.

Outlook: The brothers face their first federal court hearings this week, and the fight will center on whether the US grants the UK's extradition.
