How can you even compare a new gun law that limits magazine capacity to a trial by jury where someone died. That is worse than apples to oranges. That is like apples to elephant.
And yes, sometimes innocent people are convicted. 1% is a small price to pay for a system that works the majority of the time. Would it suck to be in the 1% group? Yes. But what is the percentage of people that were guilty but set free because of a poor prosecution, or a tainted jury, or a multitude of other factors? All in all, I think the system works, albeit slowly.
