2003, old news but okay.
While some of Harris' 2003 literature said that Harris had "tried" hundreds of cases, other campaign literature at the time said she had "prosecuted" hundreds of cases -- including her campaign website, which used the word "prosecuted" instead of "tried," according to a version of the web page viewed by ABC News via the Internet Archive's Wayback Machine.
Experts told ABC News that's an important distinction.
"A prosecutor prosecuting the case means that they were the attorney on the case where someone were facing charges. When you have tried a case, that means that case is going to trial," said ABC News legal contributor Brian Buckmire. "So the number of prosecuting cases should be a higher number than trying a case, because you may have a case that doesn't go to trial because the person takes a plea, the case get dismissed, whatever may be, you still prosecute that case. But you only tried a case that has gone to trial."
It seems there were no "experts". There was one person and he worked for ABC news as a "legal contributor". They don't even call him an expert.
