Morality of Schneider walking away unscathed at the end...
People die because of his decision to play hardball with the thugs. Being a native born Detroiter like the "52" story writer Elmore Leonard, I would have prefered a more karmic ending for Scheider for all of his nogoodniks doings.
How about he walks alone to retrieve his car after the last bad guys dies. Ann-Margaret waits for him with the $52K in a satchel some distance away. Schneider turns on the ignition only to realize that he forgot that he had booby trapped his own car. Or some such scenario.
