they can seize your assets regardless of arrest… it’s called forfeiture and it’s criminal…
this was kinda covered elsewhere on the forum a long time ago… but of course i cannot find it now… this is kinda close… Incarceration and Implants - #3 by init6 … but basically my opinion is;
they can scan you just as they can force you now to give up a fingerprint or face scan or whatever in order to unlock your phone… scanning a transponder is the same thing
push comes to shove they can remove it from you if the court deems it to be worth the risk…
