It's 0.081 and the analogy, while definitely not perfect, is blatantly obvious. The other driver killed someone (your son, in the story). Chauvin killed someone.
Also, please note, the story is for illustrative purposes only. I would not bring your son into it, had you not introduced it. Anonymous or not, as far as I'm concerned, families are completely off-limits here. I am making zero comment on your actual son and wish him nothing but the best.
I dont see the connection between chauvin and an out of his mind drunk driver. I didnt follow the trial as closely as some, but from what i gathered it wasnt an open and shut case. Obviously the jury disagreed. I am just saying i would take my son's actions into account and would be content with whatever the jury decided.
