If a criminal loses his/her fingers, makes harder to steal later on.
That is a wonderful idea.
If memory serves, he lost quite a bit of use from that hand.
Cops come out, find lots of blood on the gutter.
But nothing that would have cut him.
Nice touch by the homeowner, remove the razor ribbon but leave the blood.
Which would suggest the badguy cut himself elsewhere.
And that’s about the extent that I remember of the story.
