No.
Do you understand the concept of linear time?
Not-a-jogger Arbery wasn't "murdered" because he was trespassing. McMichael recognized him from security camera footage from a house that previously had property stolen from it, as Ahmuad "not-a-jogger" sprinted down the street from the same area as the house he was videoed trespassing in before.
The McMichaels gave chase.
The McMichaels drove past Ahmaud "not-a-jogger" Arbery and stopped to confront him.
Arbery then darted from 3 to 4 feet off of the right side of the road to near the center of the road in front of the McMichael's truck where he tried to grab a gun and was then shot.
He was killed because he tried to take someone's gun from them, not for trespassing.
I wish I could have a calm and reasonable conversation about this with you.
Sadly, even if you and I could manage it, you would be attacked from the audience, and you would shoot back. (no reference to the actual situation under discussion intended.)
It wouldn't have to be me, either. It could be with one of several other posters here who would be able to not try and escalate and insult in the process of the discussion. I would like to hear your perspective in a reasonable conversation.
So, I'll just put in my two cents, in much the same manner as everyone else, perhaps with a slightly different focus.
I agree with much of what you wrote above, and the areas of disagreement, the disagreements are rather small. Did he actually steal from that property, for example? I don't think that's established. Did they actually recognize him, or did they just think he was probably the guy? Those questions aren't really all that important.
But now we get to the important stuff. Was Arbery "killed because he tried to take someone's gun from them" I think that's a true statement. However, the statement that isn't present alters the meaning completely. What's missing is the statement that Travis McMichael pointed a loaded gun at Arbery. That missing statement makes all the difference. So while I agree with each individual statement, or have only slight disagreements with each individual statement, the collection of statements ends up being misleading because of what's omitted.
Legally, the fact that Travis McMichael pointed the gun turns it into a slam dunk case. You can't do that unless your own life is in danger, or in some cases if you are trying to protect your own property. There is absolutely zero chance that Travis McMichael had legal justification for pointing the gun at Mahmaud "no longer jogging or breathing" Arbery. Once the prosecution gets past that, Travis is done for. Roddy and dad are probably done for as well, although the case isn't quite as open and shut against them.
In my opinion, they don't have a moral case, either. I don't want to live in a world where private citizens go about threatening to kill people they suspect of petty crimes.
So, go ahead and try to convince us that Arbery was a bad person. I think you are probably right. He certainly was a troublemaker in his past, so the only question was whether he had gone straight, or at least mostly straight, by the time he was killed. Young men are like that sometimes. They are complete jerks as teenagers and young men, but one day they get a clue and become decent human beings. I have no idea whether or not Arbery had reached that point. He certainly will never have the opportunity to show it.
The important point is that it really doesn't matter. Whether Arbery is a good guy or a bad guy, I want people to use cameras to deter crime, not guns. I think Travis, and possible Greg and Roddy, should go to jail, and I am almost certain that Travis, at least, will be jailed, and I think it's likely that Greg and Roddy will, too. I know they were thinking they were doing the Lord's work, and I doubt Travis actually intended to kill Arbery when he pointed the gun at him, but I don't want people running around pointing guns. Someone could get hurt.
Take some pictures. Call the cops. Don't go all Rambo on us.
