Funny because your link directly contradicts the version of events you put forward. Not only was he killed before the police arrived but the two attackers were shot by armed police very shortly after the regular police arrived and prevented any other mayhem. AND a whole bunch of unarmed regular people intervened as well.
> Not only was he killed before the police arrived
I don't know if that can be proven. He never had a medical assessment that established that at the time, and everyone involved would have had incentive to say he was already dead to avoid initiating a confrontation with the armed attackers.
Okay he was attacked and left for dead by the attackers (although the bystanders who helped said he was dead at that point after the fact) who didn't further attack him before the police arrived or after they arrived. It doesn't make your version any less completely counter-factual because no police were there when Lee was attacked and they did in fact later successfully intervene to stop them doing anything further.
