“What is that object that the cop throws behind him before he shoots, and what is the other object laying on the ground?”

I do not know, do you?

Something was dropped by the driver. If it was a tazer, it will be obvious how far the driver fled after dropping it by the amount of wire spooled out.

What did the cop drop in the video, and what did he go back to pick it up and then drop by the body.

So far everyone, including the cops, seem to think it was the taser that you think was dropped by the driver.
