“That’s all the bullets we had, or we would have shot him more,”
Are you telling me NO ONE reloaded. It's fairly clear to me if they had more bullets the would have used them.
Seems to me you don't know crap about firearms, the police or this story.
The whole thing was over in SECONDS. No time to reload unless your Annie Oakley.
Yes they fired until their weapons were empty (no more bullets) but they did not reload and then keep shooting at a corpse.
