Because the prosecution, to placate a crowd, over charged him.
EXACTLY they Overcharged him.
And when he is exonerated of the Mass Murder charges they’ve leveled against him there will be massive protests in the streets and the media will lie about it.
Same thing will happen to that officer in Atlanta who shot the fellow who was firing a Taser at him. He is overcharged to the max so that the death penalty will be a bargaining point to get him to confess to something “lesser” like Voluntary Manslaughter. If the guy has a lawyer less venal than General Flynn’s lawyers he will get off clear and could possibly even get his job back.
And they MUST have a conviction, so the city will not burn!
