I do get it, but the only reason you know it's potentially odd, is that it was recorded and you get to listen to it. There's probably hundreds upon thousands of odd things that have happened, that you will never be able to judge because they weren't recorded.
I subscribe to "Dash Cams Australia" on youtube. Where real life situations/accidents are recorded. I watch these recordings and are bewildered by the reactions and actions I see of the people who have just been through a traumatic experience. IMO many people wouldn't think they would act like the dash cams recordings show, but time upon time watching these I see odd/strange/abnormal reactions.
Odd reactions, yes. Grouped with odd actions, odd forum posts, odd behaviour, odd dating rituals, odd past dates, odd outlines of body 'jokes', odd decision making pre and post accident, odd dialogue on the night, odd choice of phone calls... it becomes less just about an odd reaction to a trauma and more a wholly odd situation with a tragic outcome.
You know what? I genuinely hope that, despite some of the rude tones you've used in presenting your arguments, you're correct in that it was a tragic accident and he had no blame. Because if the alternative is true, then we are probably looking at someone who will hurt again, if not kill again.
I want to believe in the former option, but just because I don't, doesn't make me any less intelligent or able to look at evidence or the case particulars or anything else... we don't have to be rude to each other to disagree.
Put 2 of the most educated people in the world next to each other and they will eventually find something they disagree on. It doesn't make one less educated or intelligent; it simply means they have their own minds that interpret things differently. Such is life.
