Can you explain why? It seems like that is exactly what was implied by the recent SC judgement.

The sequence of event presented by the poster you are responding to is indeed a joke in 2024. Can you however not see a future where it becomes a practical possibility?

When the liberals on the Supreme Court say this:

> Looking beyond the fate of this particular prosecution, the long-term consequences of today’s decision are stark. The Court effectively creates a law-free zone around the President, upsetting the status quo that has existed since the Founding. This new official-acts immunity now “lies about like a loaded weapon” for any President that wishes to place his own interests, his own political survival, or his own financial gain, above the interests of the Nation. Kore­matsu v. United States, 323 U. S. 214, 246 (1944) (Jackson, J., dissenting). The President of the United States is the most powerful person in the country, and possibly the world. When he uses his official powers in any way, under the majority’s reasoning, he now will be insulated from criminal prosecution. Orders the Navy’s Seal Team 6 to as­sassinate a political rival? Immune. Organizes a military coup to hold onto power? Immune. Takes a bribe in ex­change for a pardon? Immune. Immune, immune, immune.

Then the claim that the President can in their official capacity assassinate others with impunity and protection from prosecution is no lie.

You're living in a pre-Trump world. The Supreme Court changed the rules while you were asleep.
