"It was not a shoplifting, officers responded to a call by Walmart because the derelicts were in the store and physically assaulted an employee. They were camped out in their Suburban. When the fight breaks out there are 9 derelicts total, 7 fighting males against 4 officers and one civilian."
This is a situation where the cops would have been justified in approaching with drawn guns and shooting the first person who engaged them, or failed to follow their order to stop fighting.
