By my understanding of the law. the "FBI" can not sell them until DPR is convicted, as if he is proved innocent, they may have to give them back (although i think this is VERY unlikely to happen).
no, legally they dont have to do a criminal forfeiture. they can file for forfeiture civilly without conviction. but that is unlikely to happen.
whatever happened to innocent UNTIL proven guilty......
(i was recently in court for not paying "council tax" (everyone here has to pay this if they live in a house, unless you are on a low income). when i offered a full & prepared defence i was quickly told "you must be mistaken, as you are not entitled to a defence"... needless to say, i was found guilty.... )
