Things of that nature play to us on a subconscious level. Oft times, we don't even realize it. Certain colors for certain emotional reactions, certain positions to help to invoke a sense of trust, certain clothes that help diminish stature, etc. etc. Every good attorney (and other marketers, heh!) know and employ these tactics, sometimes very successfully. If I were a defense attorney, would I use them? Absolutely. And I hope ZA's attorney uses them too, along with every other trick in the book to force the prosecution to prove their case beyond a reasonable doubt. So much the better if and when he's convicted.
