Yes. Though in practice we know it couldn't happen. Executive Branch refusal to enforce laws has happened plenty in the past. And it is an impeachable offense as far as I know. Should have been enforced then as well as now.
We don't lock up impeached officials, we kick them out of office. And that is what should happen to members of the branch of government that is designated by the Constitution to enforce the laws passed by congress. Not simply the laws it happens to like.
In fact there are so many laws on the books, a great many of them unenforced, that enforcing them all would be highly unpopular, and if it were a crime to not enforce them we could arrest every officer of the law in the USA.
But I agree with you 100%! Here in America we impeach high officials, or censure them and remove them from office. We do not arrest them, or parade them through the streets suspended on a meat hook, or hold them in prison for decades until THEY become President. We kick them out of office, at the ballot box, or through our Constitutional systems.
THAT is the American way. Not ‘after November come the trials’!
