> Yes, mens rea is a deeply-precedented standard that's a good default
(From the other side the pond) it does seem that legal standards such that one are applied very selectively in the USA, apparently depending heavily on the political leanings of those involved in any (potential) case.
On the other hand, at least you do actually run elections to pick your POTUS, this side of the Atlantic we get the President of the European Commission based on a back-room deal and a Soviet-style "vote" in the Parliament with no choice. To top it off, when she first got the job in 2019, VdL wasn't even a candidate for it during the immediately preceeding European elections.
Yes, mens rea is a deeply-precedented standard that's a good default.
