Actually it's pretty simple.  Once arrested Epstein calls his expensive lawyers.  They've been waiting for the call.  They get their hands on his list of assets and his latest financial statements.  Then the pulse quickens as they decide their time is now worth $650/hr. where yesterday it was $500.  They total the assets and divide by $650 to see how many hours of lawyering he needs.  Since the law states he's entitled to a legal defense the government can't take his assets until the lawyers are paid.  Using the above math they figure the government will end up with about $0.27 +/- $0.03 after their legal fees are paid.  Having a law degree in D.C. is akin to having a license to legally steal.  The swamp will need many lawyers in the coming months.
