Look, I recommend reading the decision, especially the first few pages, instead of basing your opinions on what you think makes sense. I’m done trying to convince you about what’s in the document, it’s there for you to read if you actually care and aren’t just arguing in bad faith.
That’s not how immunity works. It’s not a defense at trial. It’s presumptive, and prevents you from even filing charges. If you look at my screenshot above, their stated intent is to protect the president from having to go through trials.
