The thug that killed Rayshard Brooks knew that Brooks had a taser in his hand,
and could not threaten his life with the taser.
If one can believe the thug, Brooks started fighting to grab the taser
after he failed a sobriety test. I supposed Brooks feared arrest as a
consequence, but why? The thug did not find him driving the car, only
sitting in it, and that is not a crime.
Brooks' theft of a taser called for some action, but it did not have
to be immediate. So did his being drunk and in possession of a car,
since he could have started driving it and killed someone. But towing
the car should have been sufficient to prevent that. If the key was
still in the ignition, a faster and cheaper solution would have been
to move the car to where it was not in anyone's way, then hold the key
until Brooks came in, sober, to claim it.
