How can it be a good wager when "they" don't know if the someone "they" hit was killed or severely injured because "they" didn't stop? Are drunk drivers that good at assessing unseen damage on the fly? And by invoking the royal "they," how many of those four qualities (white, middle class, drunk driver, no record) exclude you from that hit-and-run calculation? And what does a clean criminal record look like, anyway? Sounds oxymoronic.
Otherwise, very well reasoned and stated.
