Arrests aren't hard to find. Just check with the county jails. EVERYONE arrested has charges filed against them, and those charges ARE public record.
For Fed arrests, the Fed charges are filed with the Fed courts and the Feds ALSO (typically) book their arrestees in local jails because they don't have the facilities, usually, and contract out the use of their locations. That's why Epstein was held in the MCC in NYC.
You need to up your game in researching, anon.
