Witness credibility is a difficult issue. When I was doing union work there were many cases I had to settle because I didn't dare put a complainant in front of an arbitrator for fear they would make asses of themselves on direct or cross examination.
Oddly, no matter how much preparation you give a witness a lot of them are like boxers. They hear the bell and promptly forget everything their trainers told them and lead with their chins.
