Anyone with eyes having seen the video sees the LEO in a shooting stance, feet about 12-18” apart, right foot to the rear. Hard to see how he was ‘tangled’ up in anything.
In parts of the video you can even see where the head holding the wires that connects to the taser body is dragging a few feet behind the victim. That’s probably why the officer’s taser shot didn’t work because the head pulled off and stopped zapping then.
So then we’re left with 8 shots fired at the victim’s back from a standstill stance.
That's less likely to cause uncomfortable breathlessness than running after him. Have a heart. You want your cops to have energy left to hand out summonses for state confiscation of funds. Politicians' brothers-in-law need funding for their no-show jobs.
