If so, then you would know that the aggravated assault is to intentionally threaten deadly force readily capable of causing death or serious bodily injury. And you would also know there are two of these charges, regarding the use of firearms to threaten and the other in the use of the pickup truck with to create a fear in Arbery of being run over.
The other basis of the other charges are that of false imprisonment, which is when you intend to constrain someone’s freedom of movement.
So you know what the prosecution claims: that these three decided with malice to unlawfully chase Arbery through the neighborhood, and attempt to and actually did threaten him with deadly force harm through the use of their pickup trucks and the shotgun.
Here is why I consider the charges and a finding of guilty to be problematical:
First, it's undisputed that Arbery was in a local dwelling illegally, a burglary and felony.
Second, it would see that the 3 were aware of that, i.e. had direct knowledge of that.
Three, under Georgia's citizens arrest law one need not be correct in that knowledge, only that the 3 reasonably believed it to be true (which it was).
Four, if you are allowed to arrest someone, then pursuit and detention are an inherent part of that and themselves cannot be unlawful conduct.
While I think absurd to claim an attempt to threaten with intent and malice, I think I see one part that is treacherous for the defense, at least in the case of the younger McMichaels. As Arbery approached the truck from the rear, be made a beeline to the driver standing next to his door, with a gun. At some point, it looked to me that McMichaels may have pointed the gun at Arbery (and perhaps issuing vocal commands) so as to make him cease running towards him - Arbery responded by veering away, running to the passenger side of the truck.
Did the younger McMichaels lose his right of self defense by illegally pointing his weapon at Arbery, thereby prompting Arbery's attack in front of the vehicle?
On that I am uncertain. BUT aside from that, I am confident that if the foregoing facts are true the 3 should not be otherwise convicted.
