I am not saying he definitely wasn’t trying to kill Mr. Jackson intentionally. I’m saying that the other possibility is that he’s a stupid coward that empties his clip at his own car because he’s terrified and doesn’t think about and/or care that there’s a person in his car.
Was he intending to kill Mr. Jackson? Maybe. That’s definitely not an unlikely possibility. But I think stupid cowardice where the motive wasn’t murder is also not unlikely because cops are stupid cowards.
