as far as the object dropped, maybe he retrieved it so it wouldn't get lost or stolen, maybe he panicked and thought it would be better close to the suspect, but his empty shell casings would show exactly where he was when he shot so he would have had to been stupid to do that..of course he would have to have been stupid to shoot the guy in the back running away, did he not see what happened to michael brown shooter? double stupid.

Ding ding ding! We have a winner!

I have no idea what the objects were he is seen picking up, dropping and then picking up.

BTW, since he was stupid enough to shoot this suspect in the back multiple times, at what appears to be an unarmed suspect running away from him, he might be a pretty stupid guy. I don’t know.

I have no idea what he was thinking or what he picked up, dropped, and picked up.

It's why I'd like to see his statement.

I don't know why they'd hold it from public view, since they already have all the evidence they're going to get in this case, including video. It should be interesting to read it as his statement was taken way before the video surfaced.

One other thing, the video will place him at or near the exact spot. As shell casings ejected are approximate. They roll, bounce, fly and other factors, they can get close but not as close as they would using the video.

So the casing are not really a factor here. And not what he picked up. Because what ever he picked up at the point of fire was one object. He was not searching around for all the brass.
