Umm there is a bit more info on that. Greg, the father and previous cop, had dealings with Arbery in the past. He was the one to investigate him for shop lifting in 2018 and knew about his prior records which included a weapons charge when he brought a gun to a high school basketball game. This wasn't Greg's first encounter with Arbery we now know. Greg had been part of the facebook page in dealing with people coming into the area and stealing stuff or moving things around at the very least.
What is going to be argued in court is if those past incidents would lead a normal person, as Greg was a civilian at the time, to reasonably believe Arbery had stolen something when they saw him trespassing again, or was casing the place with the intent to steal in the future. That is going to be a key factor in if the McMichaels get off without any guilty verdict. If it was reasonable for a person with their knowledge to believe Arbery had committed a felony at the time and may have been armed, then they are really protected by the Citizens Arrest statute. Meaning they'll get off without any charges sticking.
There are really two parts to this case. Would anyone with the evidence at had to the McMichaels have a reasonable suspicion that Arbery had committed a crime to affect a detainment until law enforcement arrived. That is issue one. Second, was the use of force use for detainment and what that constitutes. Of course if the first legal issue doesn't go well for the McMichaels, the second is going to be far worse. They will more than likely get felony aggravated assault and murder if the jury doesn't find that they had reasonable suspicion a crime occurred at all. Which I don't think that will happen because they witnessed him trespassing at the minimum. Trespass is a crime and people can affect a citizen's arrest over it in Georgia. Just like how shop keepers can affect a citizen's arrest over a suspected shoplifting incident which is also a misdemeanor crime everywhere in this country.
If the McMichaels are deemed in a court to have reasonable suspicion to affect a citizen's arrest in a court, all that means is it highly unlikely that they get felony assault and murder. That doesn't mean they are off the hook. There is still the problem with reasonable use of force to affect the citizen's arrest. This is where the nitty gritty and ugly come into play I think in the court room. Following a truck and even carrying weapons I don't think is the problem here. The issue was getting out of the truck and possibly having the shotgun pointed at Arbery at the time. That would be an escalation of force that a jury may not find reasonable to the situation. If not, Travis will get reckless use of force and endangerment charges at the least and possibly negligent/reckless homicide as a guilty verdict. I am leaning in this camp as to what is going to happen. As I have said though, we don't have all the evidence yet on this case. There may be more witnesses we don't know about, more video, and other evidence from the scene at the time. We don't know if Arbery had not stolen anything at the time either and then dumped it while escaping the McMichaels. He had previously dumped stuff from his prior run ins with the law that he was convicted of. Also, many in his inner circle had been convicted of crimes as well at the time Greg had been investigating Arbery for his shoplifting crime in 2018. Which means Greg would know the circumstances of those as well at the time of this incident.
As I said right now already several times. We don't have all the evidence. We can all express opinions on the evidence and the likely outcome of the case. I am just trying to do my best to correct mistakes other posters have made, which may include myself, on this case as it progresses for the public. I am surprised still by how much evidence keeps getting leaked out though. I would be worried about possible tainted jury pools if I was handling the investigation of this case.
