One of my electrical instructors at college is also an expert witness (for the state, insurance companies, etc.) - he told us of a case involving a fire...they wanted to sue the electrician for something he had nothing to do with....electrican felt pretty safe as he had nothing to do with the fire....started somewhere else in the bldg. where he had not done any work....the lawyer gets him up on the stand and asks if he has a calibrated inch-pound screwdriver....electrician says 'no' and the lawyer proceeds to turn to the jury and explain how it is the electricians fault for the fire because he didn't install any the the panel/breaker equipment per mfr's specifications...etc, etc...."thus causing blah, blah, blah".
