Witness states she put down the bottles before she left the store.
Whether she did or did not take the bottles is completely irrelevant to the shooting. A complaining witness claimed she had; officers had sufficient cause to conduct a stop and investigate that complaint.
The description of the video states she accelerated towards an officer. The video shows an officer step in front of the slow rolling vehicle.
The video shows an officer stepped in front of a stopped vehicle. That vehicle was later driven toward the officer. The description is accurate; your claim is not.
Pedestrians have the right-of-way over vehicles. Even if she was moving when he stepped in front of her, she was obligated to stop, both under traffic laws, and per the lawful instructions given by the officers. She was not justified in driving toward the officer.
She escalated from being suspected of shoplifting to committing assault with a deadly weapon.
He was also able to safely get away from the slow moving vehicle after he fired a shot, something that he could have done before choosing to end a life
That might be relevant if he had a “duty to retreat” from the assault. Do you believe he had a legal obligation to retreat? If so, under what legal theory do you believe he acquired that obligation?
