There are understandable reasons for the rules about when evidence must be introduced, but these rules can sometimes be abused by people who withhold evidence until it will no longer do any good (as is alleged to have happened with some of Terri's medical records in the extant case). Perhaps there needs to be some sort of adjustment to the rules?
Definitely.
When I grew up, the "sense of the nation" was that it's better for ten guilty to walk free, than for one innocent to hang.
Now, we've embraced a cold, brutal, soviet style "justice", in which the "letter of the law" has replaced any semblance of due process for the accused.
God help us for what we've become...
