Until the last few seconds of the encounter, Rosenbum was living the dream of a hero. Then he realized he was dying an extremely pointless death for a stupid cause. RIP
And the judge should take serious action against prosecutors who lie. Ultimately they should be barred from practicing law.
If the prosecution were truly interested in justice, they wouldn't be bringing the case at all. They're obviously interested only in getting a guilty verdict.
There are likely some in the jury with also the same interest. It seems to me that the purpose of showing the video is to tell these people that they can ignore what they 'seem' to see, and vote guilty anyway.
