Had they charged her with the appropriate crime (negligent homicide), they probably would have won the case. But apparently sending her to jail for many years wasn’t enough; they wanted her dead. So, they went for murder despite having no proof of premeditation. The judge should have dismissed the murder charge after the prosecution rested; that he didn’t is a travesty in itself.
There is absolutely no evidence for murder in this case, and anyone who thinks you should convict someone of a crime they didn’t commit because the state failed to charge them with a crime that they did doesn’t deserve to call themselves a libertarian.
State law is useless, anyway.
