I think the reason why US went with officials can still “serve” even dead is to avoid political killings (or to avoid a loophole in “justice system”, just like mitch mcconnell who is probably acting having a seizure on his live speeches to avoid heavy charges because he knows the fed knows he has a huge role with trump shenanigans annnnnd unfortunately, it is challenging to press charges against persons who has “mental” illness and stroke can be considered as one).
