Positive Law
Eric Peters Autos - good screed on the crimes under color of law that make up most of police activity these days.
Positive law is a moral nullity.
Except, of course, with regard to enforcement. A speeder hasnt committed a moral wrong, but the cop who pulls the "speeder" over (euphemism check; what hes doing is forcibly waylaying a morally innocent person at gunpoint; he is not asking his victim to pull over for a chat; he is demanding the target submit and obey . . . or else) is committing a moral offense.
A crime, arguably.
The crime of physical assault.
Clovers will contend that no assault takes place. Which is true, provided one does as ordered. Provided one obeys every barked command. If one accepts this Cloverian logic, then every battered wife only has herself to blame. Look what you made me do, exclaims her boyfriend/husband.
