To be a bit pedantic, its not sovereign immunity, its qualified immunity. It is defeatable, and there are examples of it, but its rather rare. It is an abused and obviously problematic legal doctrine
>In court filings, attorneys representing the state and Bradley have argued Holland's lawsuit should be dismissed as the trooper has "sovereign immunity" as a member of law enforcement, and that it was a "lawful" traffic stop.
The concept is right but sovereign immunity is about states and between states.
