Fucking hell that is horrible. And of course she's the only one to survive. 100mph into a brick building has probably left her pretty physically fucked up and in constant pain. Hope she enjoys feeling that way in prison for the rest of her life.
She'll spend 8 months in prison and appeal for a reduced sentence and get out on "good behavior" before she's even served a quarter of her term. Don't you know how the American legal system works?
The bullshit sentences are the ones we mainly hear about, and many people have a bit of a confirmation bias because of it. But, you don't have to look further than your own community to see that slaps on the wrist are not typical.
US citizens are the most incarcerated people on Earth, by an uncomfortable margin.
Murder with a car is often toned down to, "vehicular manslaughter". It's often times charged as a misdemeanor. I agree with you that it should always be a felony because it's murder, but that's not how the courts treat it.
