As I said in an earlier post, any competent attorney would recommend SA take the plea deal, but if he's arrogant enough and stubborn enough not to take it, that's on him.
Interesting that the lawyer would prefer a jury trial. He's probably counting on the jurors feeling terribly sorry for this older gentleman who lost his granddaughter, but on the other hand, if the jurors get a good look at the window - how high up it is, how it's easy to see which windows are open and how incredibly dangerous and reckless placing a child up there is - their sympathy might just evaporate.
