The discouraging thing to me, and it shows up in that tweet, is that there really only seems to be two prevailing opinions.
1. She was brutally and unlawfully murdered. 2. She killed while attempting to run over a law enforcement officer.
There doesn’t seem to be any middle ground. Which, imo, is where the truth is most times. As it is in this case.
I don't read Shermer as saying its clear that she attempted to run over the ICE agent. I think he was saying she clippped him, but it could have been (I think it was) unintentional.
