To me, it stands to reason based soley on the axiom-
If you want more of a thing or behavior, you make it cheaper, safer, and more convenient. If you want less of a thing or behavior, you make it more expensive, hazardous, and inconvenient.
I can not think of much of anything that makes a street criminal's vocation more potentially expensive, hazardous, and inconvenient like the increased likelyhood of a controlled pair of supersonic jacketed hollowpoints to the chest...... just not worth it ..... the Identity Theft racket is much less risky, and potentially more lucrative than violent crime these days.
