You can tell he was not going the wrong way. Look at the on ramp in the video.
Motive?
Maybe getting from point A to point B.
OK, the cops’ statements are contradictory, but why did he go through the barrier which closed the ramp? Was there no other way to get from A to B?
I don’t think killing a couple of protestors was the motive for what he did. I think he was just acting irresponsibly and that led to the incident. Maybe he thought that he had rights that other people don’t have. Some people are like that.
The police report will be interesting. I’m sure they have the readout from the car’s black box.
