It would make for better jury decisions.
I believe that juries should be allowed to do their own research into any case that they are hearing and deciding on. If you are on a jury and have to decide on something then surely you should be allowed to investigate the facts yourself. One of the key reasons this wasn't possible before is that the courts weren't allowed to talk about previous convictions. Now, most previous convictions are unveiled to them anyway. So why shouldn't juries be allowed to do their own research into the evidence and facts in the case?
