I watched the video. I wholeheartedly disagree with your assessment. What I saw was two officers crossing the street in normal foot traffic. As they got close to the attacker, who was standing there non-threatening in the crowd, he lunged at them with a weapon that was likely difficult to see from their perspective or was hidden. The man attacked one officer repeatedly spilling out into the street. The other officer shot him. That's about as clean a shoot you can get. There was no way that situation was going to be deescalated by talking him down. He attacked them before anything had escalated in the first place. What would have been an incredibly stupid thing to do was for the second officer to engage the attacker by physical means instead of drawing his weapon and shooting him. An incredibly stupid thing that you seem to suggest should have been done. Or maybe you mean the second officer should have deescalated the situation before falling back on drawing his weapon even though the situation was the attacker beating his partner to death in the street right in front of him.
