As far as I can tell - FTX (at least international / not FTX.us) broke only 1 law - they broke their own terms and conditions :-
8.2.6 All Digital Assets are held in your Account on the following basis: (A) Title to your Digital Assets shall at all times remain with you and shall not transfer to FTX Trading ...
Excluding this stipulation, which they will be prosecuted for - what exactly the CFTC/SEC/NYSE/NASDAQ/Secret Service/DEA/Texas Rangers were meant to do about a company in the Bahamas is beyond me.
