Nixon v Fitzgerald was decided in 1982.
I really don’t know if you understand the difference between civil and criminal law.
I don’t know how many times I can say this…if your actions lead to the death of another person, that is not a civil matter, it is a criminal matter.
Nixon v fitz.. just said a president has immunity from civil damages for any official action taken while in office.
We have immigration LAWS, if Biden fails to uphold those LAWS and refuses to secure the border, and one of those illegals ends up murdering someone, then the argument can be made that Biden, by willfully ignoring our laws, created a reckless endangerment of the citizens of the country that directly led to the murder of one of its citizens.
That can be considered negligent homicide, or even manslaughter. Those are criminal statutes.
Same thing with operation fast and furious, where the Obama administration was carrying out an illegal gun running operation, and some of those guns made it into the hands of the cartels which used one of those guns to murder a border patrol agent.
Again, that is a criminal act.
Since the court ruled that criminal actions taken while in office are not under the immunity clause, those families can sue under criminal statutes for recompense for their losses.
