I cited you to a Supreme Court case that concerned exactly this sort of situation.
You typed the name of a Supreme Court case without providing a link. In other words, you expected me to do your research for you since you were clearly too lazy to read and then provide a link yourself.
Fortunately, I was able to do what you were not willing to do yourself, and researched the case. If you had taken the time to do so, you would have saved yourself the trouble of looking like a complete fool. Kalina v. Fletcher is a civil case - not a criminal case. The immunity provided is protection against civil judgment, not criminal prosecution.
Nice try though. Maybe next time, you will do your own research the next time someone on another website like DummieUnderground hands you the name of some court case.
Have a good night.
