That was cold blood
They killed him because they thought he stole their gun a few weeks ago
These three fools chased this guy around a development, struck him with a truck, blocked him in twice and finally shot him dead, three shot gun blasts.
That is cold blood.
These fools deserved the electric chair
Arbery was not shot 3 times.
He was shot once, and that because he grabbed the wrong end of a shotgun.
The McMichaels were trying to apprehend the perpetrator of a string of property crimes. They pushed the attempt too hard, introducing lethal force into a situation not warranting it. Arbery pushed back, eventually grabbing the muzzle of a gun - either that caused it to fire, or McMichael fired.
It wasn’t cold blood. Ambiguous as to who actually caused the gun to fire. Both McMichael and Arbery were acting in such a manner: McMichael by pointing it at Arbery with his finger on the trigger, Arbery by pulling on the gun.
Arbery had opportunity to disengage, but didn’t - opting for a “stand your ground” form of proceeding down the street as best he could (vs leaving the road, and thus the pursuing vehicles).
McMichaels had opportunity to disengage, but didn’t - forgetting he wasn’t a cop any more, he attempted to apprehend a property crime suspect. The suspicion wasn’t enough to warrant apprehension, and not enough to warrant introduction of deadly force.
As both sides wouldn’t back down, it escalated as it did.
They don’t deserve the electric chair. They didn’t intend to murder him, just apprehend a suspected thief.
This is comparable to a SWAT team raiding the wrong address, and someone dying in the process. Wasn’t malicious so doesn’t warrant capital punishment, but neither can they be let off with “oops, sorry”.
