If the accounts are accurate, the body cameras are irrelevant. Apparently, Ms. Damond was talking to the officer on the driver side and Noor reached past him to shoot Ms. Damond.
Mohammed Noor has been in trouble before re his treatment of a woman, a social worker, who called police and ended up being arrested by Noor and sent to Mental Health (from which she was quickly released.
IMHO, Noor sounds like he has some mental health issues of his own.
And Minnesota seems to have problems with cops who are too eager to shoot.
