So, a lawyer who is an expert in the law of self-defense wrote a long column examining the legality of three sets of shots, knowing from the video the effects of each set. The shooter had 2 sec, 0:14 to 0:16 on the video, to do the analysis.
And a jury sitting in an air conditioned courtroom will see the same evidence (in addition to whatever else the defense and prosecution can come up with).
The learning opportunity here is to evaluate the defender’s tactics, and try to learn from what is both legally and tactically “safe”, and distinguish that from what appears to be great legal peril.
Your point about the effect of time pressure is spot on, and one hopes that his counsel will remind the jury of that as well.
