I'm imagining a conversation. "I am also willing not to shoot people for a thousand bucks a month. I mean, contingently. There may be the odd month where somebody really just needs shooting. But I've got a pretty good record going, so..."
"That's just why you're not eligible. Your good record is pretty uniform. We only pay people who kill people sometimes. You weren't going to shoot people anyway."
"Well, probably, but now I'm thinking that I need to get on the list of people you want to pay off..."
They say they've had good results. I'm sure they have. What I wonder about is whether this is the sort of thing that doesn't set up perverse incentives over time.
