I mean, thanks to Obama, the president has the authority to kill any US citizen they deem as a threat. The ACLU brought a case against the government about that, but that case was dismissed on procedural grounds, so it’s still constitutionally untested. But regardless of it being tested, there is precedent for it, thanks to Obama’s murder of Anwar Al-Awlaqi. And since the precedent says that the murder by the executive branch of any US citizen it deems a threat is kosher, well that would fall pretty nicely under the heading of “official acts of office” that this latest supreme court case showed would be absolutely immune from prosecution.
So I guess the question is: does Biden feel like murdering a bunch of citizens?
