Never said there was no bias, but I"m reading around the bias to the facts they present. If those facts (ignore motivations, cant say what those might have been) are true, and the video shows what they claim it does, then the officers and the witness are done. Any officer who might mistake this for a shotgun should be assigned to a desk, one in say an insurance company office.

Now, does it look like it might be a scary "assault rifle"? Sure does to the untrained eye anyway. Good things officers are trai...... never mind. Even so, if the video shows him raising the weapon towards the officers, I would go with it being a good shoot. But I'll bet it doenst. Nothing to hang that on but my gut, but I'll trust it.
