It is absolutely highly concerning. That said, there's way too many people who haven't read the official ruling who are panicking instead of advocating for people to vote to keep Biden in office and prepare another viable candidate for that office once his second term is up. Because the only way to get these idiots off the SCOTUS is to elect non-conservative presidents who can win. And that only happens if people both vote and lobby for what they want. We need better electoral college regulations. We need ranked voting. We need the people to lobby to further limit the government because obviously this is what happens when we don't.
This ruling, coupled with the whole "Biden is too old, he should step down" BS is exactly the kind of propaganda concoction that will lead to Trump being re-elected in November if we don't do something.
Do I think this is a way for a President to sanction and enact the murder of political rivals? Under certain circumstances, yes. Do I think the average citizen should be worried about the President signing their death warrant? No.
You have to understand that we've had alphabet agencies for a long time and the President literally could use certain pretexts to kill a person if they wanted so long as they did it a specific way. That has not changed just because of this ruling and that's a big factor people should look at. There's a reason former Presidents haven't been prosecuted for drone strikes. Technically they could have been held accountable in a court of law before that. But we've known for a long time that in all actuality the law only works that way if you're poor or if you're going up against someone else who's independently wealthy. That's why Epstein is dead after all. Not because he trafficked young girls. But because his imprisonment put other rich people in danger. Sam Bankmanfried isn't in prison because he stole money. He's in prison because he stole from other rich people. Same with Elizabeth Holmes.
When Trump was in office, I need you to understand that the government (the people who guard national secrets) actually considerered him a threat and limited his ability to do damage by not telling him things. We would have been much worse off if they hadn't.
As a result, the apparatus of the government is not a monolith, just like the apparatus of the military or even just the US as a whole. It's made up of people. And we've limped along this far because we could rely on them not to do certain things. But what Trump was able to get away with by being elected and being in office? This is the fallout of that.
Your statement that the president can "personally" violate any law without criminal liability isn't correct. Here's a direct quote from the ruling "Held: Under our constitutional structure of separated powers, the nature of Presidential power entitles a former President to absolute immunity from criminal prosecution for actions within his conclusive and preclusive constitutional authority. And he is entitled to at least presumptive immunity from prosecution for all his official acts. There is no immunity for unofficial acts."
"As for a President’s unofficial acts, there is no immunity. Although Presidential immunity is required for official actions to ensure that the President’s decision making is not distorted by the threat of future litigation stemming from those actions, that concern does not support immunity for unofficial conduct. Clinton, 520 U. S., at 694, and n. 19. The separation of powers does not bar a prosecution predicated on the President’s unofficial acts."
On its face this ruling admits there is a such thing as an unofficial act. The problem is that the SCOTUS should not be allowed to make this decision without checks or balances in place. I.e. if they are making the deduction that a President has immunity, they must cede the determination of such acts that have immunity vs those that don't to another regulatory body. That's the disturbing part to me.
This also makes me question what the point is of the impeachment process specifically because of this passage from the same ruling:
"When the President exercises such author ity, Congress cannot act on, and courts cannot examine, the President’s actions. It follows that an Act of Congress—either a specific one targeted at the President or a generally applicable one—may not criminalize the President’s actions within his exclusive constitutional power. Neither may the courts adjudicate a criminal prosecution that examines such Presidential actions."
Technically an impeachment is not a criminal trial. But that passage doesn't specify the scope. So it could be used to argue that impeachment (while not a criminal proceeding) is an examination of the Presidents actions that potentially would not be allowed. And since the impeachment process is a check and balance for the presidential office, that's not okay.
