Sometimes, decisions must be made by an expert on the spur of the moment. One cannot prepare for all unexpected events. Here is an example.
Nothing is more embarrassing or potentially catastrophic to any forensic expert than to find out while in court that additional documentation or evidence relevant to your opinion has just shown up. This case involves Werner Spitz (pathologist) in South Africa experiencing such a scenario. Here is Spitz in SA.
I’ve had this happen a couple times. I once didn’t receive evidence vital to my opinion until the night before testifying. Later, after eventually testifying a month later, my opinion had changed due to this evidence. The opposing counsel dreamed up a scenario that I had only changed my opinion in order to get more money. The truthful answer I gave was “No.”
Years later, some scoundrels came up with the scenario that I had said “Yes.” They admitted such tripe into their courtroom arguments in a number of criminal cases.
