You are making up stuff out of thin air....he was not cornered ....he had freedom of movement at all times.....the video shows him freely jogging down the road like he didnt have a care in the world.By their own admission they were chasing him through the neighborhood and trying to cut him off to stop him for questioning. There's no law that I know of that allows someone to grab their gun, form a posse and chase someone down in an attempt to hold them for questioning. Especially when the people doing the chasing had not witnessed any laws being broken. As you know Ahmaud Arbery is under no obligation to stop and talk to these guys. They cornered him after an illegal chase and he fought back. Ahmaud was probably tired and scared as shit.
There was no attempt made to arrest or hold ahmaud.....McMichaels was a former cop deputized to deal with the likes of amaud.....he had been a cop for 30 yrs. thus very experienced in how to subdue and arrest someone and would have had no problem doing that if that is what he had wanted to do.
Sr. McMichaels did 3 things......attempted to talk to ahmaud to find out what he was up to and then kept him under observation and called the police.
