None of the above. My answer is much more mundane. Krebs almost certainly has professional liability insurance (if not, that would be pretty dumb at his scale)

None of the above. My answer is much more mundane. Krebs almost certainly has professional liability insurance (if not, that would be pretty dumb at his scale) I would call up my insurance company, tell them i've been sued, send them the documents, and then go back to my day. I would then proceed to follow their instructions, and not care too much about it, unless i was asked to do things that i wasn't willing to do
