Did the McMichaels witness or have immediate knowledge that Arbery committed any offense? The presumed offense would be trespassing. It does not appear so. Greg says he was standing on his lawn when he saw Arbery running down the street. Travis was in the house. Neither were in the presence of any offense.
Travis had confronted Arbery standing on English’s property about two weeks before. That raises the question whether that constitutes immediate knowledge of an offense. It appears the phrase “immediate knowledge” is not defined in Georgia law and that it is not even a common legal term.
The “immediate” part does not appear to mean that the offense just happened recently. Although that does raise some issues about how long after an offense a person can make a citizen’s arrest. If someone sees someone committed a simple misdemeanor and then they run into that person two years later, can they arrest that person? Probably not, but it isn’t laid out in the law.
The term “immediate knowledge” basically means direct knowledge. Knowledge that is not based on hearsay or putting a bunch of clues together. For example: a person is standing at the end of a fence with a road on the other side of the fence. They hear a car crash on the other side of the fence and then see past the fence a car drive away with a banged up front end. They look around the fence and see a parked car with the side smashed in. The person didn’t see the car crash into the parked car, but they have immediate knowledge that that is what happened.
It could be argued that Travis had seen or had immediate knowledge that Arbery had trespassed on English’s property from the confrontation two week ago.
But it is not clear that Arbery even committed criminal trespass. Here is the relevant law:
A person commits the offense of criminal trespass when he or she knowingly and without authority:
(1) Enters upon the land or premises of another person…for an unlawful purpose;
(2) Enters upon the land or premises of another person…after receiving, prior to such entry, notice from the owner, rightful occupant, or, upon proper identification, an authorized representative of the owner or rightful occupant that such entry is forbidden; or
(3) Remains upon the land or premises of another person…after receiving notice from the owner, rightful occupant, or, upon proper identification, an authorized representative of the owner or rightful occupant to depart.
Arbery was not given any proper notification. If there were No Trespassing signs that might be a different issue, but I had not been able to readily see any in the videos. That leaves the question of whether Arbery entered the property for unlawful purposes. We don’t know. And neither did the McMichaels.
So, this isn’t a slam dunk case. There are some questionable issues. But I think there is a string case that the McMichaels could not have made a lawful citizen’s arrest under this standard.
