I've seen on several forums (and/or members thereof) around trades where they say they don't give advice to non-pros because they're afraid the amateur will do it wrong and they'll be found liable.
I've tried googling this question to see if it's ever happened but it seems most of the answers are around libel laws.
To expand on the question, has there been any cases where a professional has been sued/tried and been found liable/guilty for having given advice that wasn't correctly followed leading to an incident? If so, have any of those resulted in a finding of guilt or liability? What were the specifics of the case?
I'm primarily interested in the US but stories from other countries would also be interesting.
