That’s all true for premeditated crimes by someone mentally healthy enough to be processing likely outcomes and consequences, and making a very rational decision whether to crime or not.
Fact is, the vast majority of criminals are dumb, or mentally ill, or both. They aren’t doing an ROI analysis.
If you think speeding and murder are mere differences in degree, at that a mental model of a typical speeder also applies to a typical murderer, I guess I could see a “highway patrols deter speeding, therefore beat cops deter murder” argument.
It’s a little hard to keep a straight face though.
