He’s the commander in chief, ordering a seal team or the CIA to assassinate someone is an official act and legal now. What you fail to mention in your haste to try to downplay this is that they also made it impossible to present evidence of crimes by the president, so any non-public action by the president is de facto legal. It would be impossible to prosecute because even if you gathered evidence he ordered the hit, you couldn’t use it in court.
Yes, it’s that bad. No, it’s not that people are over reacting.
Read Sotomayor’s dissent, she says explicitly that this gives the president legal immunity against assassinations.
