"My friend said she told her brother "Spoken like a true, well-off, authoritarian, white male who'll more than likely never be stopped and murdered by the police.""
The friend sounds like the over- the- top, ultra- stereotypical parody versions of SJWs that conservative commentators like to use for comic relief in their youtube videos. All that was missing was for her to shout in an exaggerated way, "Your racism is TRIGGERING ME! I need to go find a puppy to pet and an adult coloring book to channel my frustrations in."
Back to the topic at hand, while I don't think they'll be getting life (Though Montel is right that they deserve it), based on the charges they're facing and typical sentences for such charges, they should each be realistically looking at, at the bare minimum, 20 years in prison.
