A: Keep him off the stand. Which was almost certainly the prudent, if woebegotten, decision today from Jerry Sandusky's lawyer, as recounted here.
That said, this was one of the most pathetic performances by the defense I have seen. The prosecution's case probably was unbeatable, but if it was to be beaten, the only way to do it was to put Sandusky on the stand and hope he could lie his way to an acquittal, or at least a hung jury. Simply to put his wife and a few old friends and colleagues on the stand to say that he was Mr. Nicey and they never saw him do anything "inappropriate" was about as lame as you can get. Yes, thanks very much, I think we all knew beforehand that pedophiles generally don't conduct their business in front of their wives.
The only possible reason to have gone to trial was to fulfill the routine, bravado defense promise, usually made at the time of arrest, that we shouldn't "rush to judgment" until "all the facts are known" and the client has "had a chance to give his side of the story in the proper setting."
Right. Only there has been no rush, all the facts are on the table, and, when the defendant had a chance to "give his side of the story in the proper setting," he decided to pick the lint off his suit instead.
