That doesn’t apply here since the two men were the aggressors by their own admission. The jogger had a right to defend himself. At that point, that was the only way he could have come out of it with his life.
You don’t know that. The police were on the way... He could have sat down and waited.
The father was a cop who had interrogated the perp on a prior charge. They knew each other.
And how did that work out for Mr Arbery?
One could just as easily say that if Arbery had successfully wrestled the gun away from McMichael he would have killed McMichael with it. We don't know that. And we don't know what would've happened if Arbery had just kept jogging past. He had already jogged past the guy in the back of the truck without incident. What we do know, because it's clear on the video, is that Arbery attacked McMichael.
1. Carrying the shotgun was legal.
2. Trying to make a citizen's arrest was legal because the McMichaels had a reasonable suspicion that Arbery might be the one who was recently burglarizing neighborhood homes.
3. Street cops make arrests nearly every day. Cops carry guns every day. They don't use them on every arrest, in fact it's rare that they have to use their guns. So why do they carry guns? The answer is: just in case. Why did McMichael have a weapon for this attempted arrest? Just in case. And in this case he had to use it because he was clearly attached.
This case is similar to the Michael Brown case where officer Wilson was attacked and had to use deadly force as well.
In the end, Treyvon Martin, Michael Brown, and now Ahmaud Arbery all died for the same reason: they attacked men who had guns. Sad but true.
He was not defending himself. He was attacking people who had confronted him. He made a foolish attempt to rush his antagonist and grab a shotgun. It ended badly, as such actions usually do.
And he was not a "jogger". He was a burglar, casing the neighborhood for future targets.
The aggressors as you put it had already called the cops, so they were attempting to detain him, not kill him.
He tried to take the gun from the guy, at which point he lost his life. He was shot twice, one of the shots went through his hand and into his chest, which proves that he had his hand on the barrel of the shotgun. Pulling on the barrel could have been what made the shotgun go off in the first place.
