lawfag here
there is no EO that impacts indictments - the bog EO was property forfeiture and is not direclty related to arrests - i do not know what the process is under that EO it is not specified but i am sure there are evidentiary requirements and due process - i would guess they proceed under RICO like civil OR crimonal charges - in the latter case there would be an indictment in the civil just a forfeiture notice
you maybe be thinking of the new military
justice code that goes into effect 1/1/19
in that case NO arrests would occur if the intent was to proceed under the new rules until AFTER they go into effect
