All I ever need to ever see.
Irrelevant, counselor, poignant, but irrelevant.
The facts:
He was operating the vehicle. The assumption he was in full control will be a matter for the court.
His vehicle plowed into a crowd with significant force, and either in that impact or in extricating his vehicle (presumably under his control) people were injured and one died of those injuries she sustained.
Motive is a matter for the court to ascertain, and whether there was intent, rationality was crippled by fear, or there was an accident are findings yet to be made.
At a minimum, without political complications, I see involuntary vehicular manslaughter. At the other end of the spectrum, Murder 1. The final charges, and I predict either a conviction or a ruling of insanity, will likely fall in between. I do not think the young man will walk.
