After the shooting. But, she also said that Castile announced he was armed. We can't be sure of the sequence without a recording BEFORE the shooting.
I have followed this story and think the cop was wrong - dead wrong.
I think mistakes were made, but most likely by both sides. That's why I'm not trying to assign blame -- I'd rather see measures to prevent it from occurring again.
I read there is dash can video but it hasn’t been released. Not surprised.
I don't know if the dashcam video will be very helpful, since Castile never got out of the vehicle, and was probably out of the field of view.
Two cops involved so maybe two separate dash cams. Hope they are released.
