I agree that juries want the whole story laid out for them if the prosecuters know it. The whole "Closing Arguments" is where the prosecuters will usually try to give the story of what, how, and why things happened if they know it.
They should only do that if they really know for sure though because sometimes it seems like closing arguments have some theories in them and I think that can lose a case for prosecuters when they go too far out on a limb with their theories of why things happened. Sometimes its best to just stick to what they have proven and leave it be at that.
IMO, the Jodi Arias trial prosecuter went a little too far out on a limb with certain specifics that were uneccessary like the timing of when he was shot.
It didnt matter when he was shot because she stabbed him so much anyway. The timing of the shot became a big rigamaroo and IMO the prosecuter could have just not tried to say when it exactly happened.
Things like that they need to be careful with.
Dont get me wrong. I love Juan though and cant wait for the sentencing re-try of Jodi.
