What's the police version of events?
After the first shot wounded Brown, Johnson said, Brown ran and Wilson chased him. Wilson then shot Brown in the back, and Brown stopped, turned with his hands up, and said, “I don’t have a gun, stop shooting!” according to Johnson’s account to MSNBC.
But, Washington University law professor Peter Joy said, “If Michael Brown was trying to surrender at the time, that makes this defense not applicable. So the question is: Was Michael Brown clearly trying to surrender at the time that the fatal gunshots were fired?”
