No-one was shot 'while beating a police officer to death' because there was no incident where a police officer was 'beaten to death'. Officer Sicknick was hit in the head with a fire extinguisher thrown from the crowd. He was also pepper sprayed. He collapsed and died some time later, almost undoubtedly as a result of that.
OK, then for accuracy: The crowd threw a heavy object at one officer, that struck his head and caused him to die shortly afterwards of a head injury.
The crowd also pulled and officer from a Capitol doorway by his helmet; then kicked, punched, and beat him with available clubs to the extent that AIUI he suffered a mild heart attack. Now admit it - if one of your oppos was dragged out of the line so that a bunch of rioters could tapdance on his skull (because they ripped his helmet off), wouldn't you be all the way through the Yellow Card, with the employment of lethal force fully justified?
Interesting you should mention Ferguson. That started after claims of a racist police officer killing an unarmed black man who was surrendering. All of the evidence proved that the shooting was actually a result of Michael Brown's unprovoked violent attack on the officer and all the 'hands up don't shoot' stuff was lies.
If you want to discuss the facts of these incidents then I have no problem with that. It is literally what I do for a living. If you want to discuss made up emotional crap you have got from Twitter or similar I will give it a miss.
I'm willing to acknowledge that Michael Brown's shooting was justified;
as you say, the FBI investigation supports that. However, I didn't mention his name and wasn't referring to that particular incident - but to the wider investigation, that resulted in the official Department of Justice report on Ferguson PD. Note that Ferguson was a
sundown town until the 1960s, but is now 67% African American.
From page 7:
Of the 54 sworn officers currently serving in FPD, four are African American
From page 16:
FPD’s approach to law enforcement has led officers to conduct stops and arrests that violate the Constitution. We identified several elements to this pattern of misconduct. Frequently, officers stop people without reasonable suspicion or arrest them without probable cause. Officers rely heavily on the municipal “Failure to Comply” charge, which appears to be factually unconstitutional in part, and is frequently abused in practice. FPD also relies on a system of officer-generated arrest orders called “wanteds” that circumvents the warrant system and poses a significant risk of abuse. The data shows, moreover, that FPD misconduct in the area of stops and arrests disproportionately impacts African Americans.
From page 28:
Furthermore, as discussed in greater detail in PartIII.C. of this report, Ferguson’s pattern of using excessive force disproportionately harms African-American members of the community. The overwhelming majority of force—almost 90%—is used against African Americans.
From page 78:
FPD also has not significantly altered its use-of-force tactics, even though FPD records make clear that current force decisions disparately impact black suspects, and that officers appear to assess threat differently depending upon the race of the suspect. FPD, for example, has not reviewed or revised its canine program, even though available records show that canine officers have exclusively set their dogs against black individuals, often in cases where doing so was not justified by the danger presented.
