It's massively encouraging that this could happen; that the 'blue wall' was breached - well, flattened - and a jury was unanimous in convicting an officer.
After all, every system delivers what it is designed to deliver, even when this differs widely from its stated aims. And a just verdict, or rather verdicts, was delivered, so we know the justice system isn't actually broken, nor is it unfit for purpose, it's just been bent or twisted too many times in the past.
More needs to be done to consolidate this sound result, including changing the law around partial immunity for police officers and doing some defending so police forces are not gleefully stockpiling military grade equipment that they then itch to take into battle against those they are sworn to protect. 😕
Protection for whistleblowers and an obligation on everyone to speak up instantly if things go wrong on the job, even if it means challenging a superior officer, need to be put in place, too. If Lane or Keung had pushed Chauvin a bit harder on rolling Mr Floyd into the recovery position, there's no doubt he could have emerged from the encounter alive.
And, hell's teeth, let's see some effective de-escalation go into officer training! If someone had sat Mr Floyd down on the doorsill of the squad car and just said, "Take a few deep breaths, then tell me what the issue is with getting in, and we'll work out what's the best way forward together," what a difference that could have made!
