If they jury truly had no choice in this case, Then I feel it stands to reason Jury's don't have enough power in our legal system, The whole idea of a jury is to bring the common citizen to the legal process, and hopefully some common sense to the law.
Not being able to save an injustly, if lawfully, accused man for the crime of not knowing all the paperwork a disgusting flaw in our system.
I would hope articles such as this bring the issue to life in the political arena.
