Good catch. I finally see the hammer. I agree that is what he was doing, filming the hammer in the street. Which tells me that he had no idea that someone was about to be shot. He was more interested in the stolen hammer for a few seconds than anything else.
And the bad guy made quite a deft move. A fake left, then around the right side of the truck and hooking around to attack the guy from the front of the truck.
And don’t kid yourself. Thugs and yardbirds practice moves like that for use on cops. There are numerous prison videos of convicts practicing on each other. He wasn’t some “jogger”. He made a stupid move and got killed. And two imperfect but well-meaning guys got their lives torn apart by his crime and reaction to being caught.
They were the good guys, he was the bad. And two 85 year olds paid for it with their life up in that cemetery.
There's a lot of hate out there. It's a shame, but we've all gotten away from religious teachings here in America.
