Before derailing more on socks, the toenail observation came from the autopsy report which said both his fingernails and toenails were dirty.
I watched some of the closings, and I think they do have a decent shot at acquittal, if they do successfully tap into suburbanite fear of encroaching crime. The only witnesses the defense called were neighbors to ask them about how crime has been increasing in their once very safe neighborhood.
The state is saying the defendants were the initial aggressors so had no right to self-defense, while the other side is arguing that they we're lawfully trying to make a citizen's arrest. The law says you have to personally witnesses a crime to do an arrest, unless it's a felony when you can arrest if you have probable cause, a lower standard. The felony would be burglary. Arbery was caught on video trespassing but never burglarizing, but they're arguing that Arbery was likely a burglar because things were stolen at the house that he was caught on video. So when they saw him that day they had probable cause to arrest.
I think it could work, especially with how juries love to let you kill anybody you want so long as you say you were scared, especially if you're a cop or acting like a cop (Rittenhouse, Zimmerman).
