Purely from a defense stand-point - I
never thought it was a good idea for AM to take the stand in his own defense. IMHO he was a
fool for doing this. I.e., he definitely wasn't credible & made himself look
far worse - than if he hadn't said anything. He's a liar, and that was proven beyond the shadow of a doubt. This type of situation is exactly why defense lawyers warn some of their clients against taking the stand - especially in high-profile cases like this.
So, if he hadn't taken the stand - it's
possible the outcome would have been completely different. However, obviously we'll never know at this point. And, since he was found guilty - the outcome here was obviously the most optimum
