Our laws can be friendly to those who obey them, and too often useful to those who don't.
    
Cullen Hightower
[Among the most useful laws to those that disobey them are the laws that attempt to ban or restrict goods or services.  The black market always finds a way whether it is something physical like booze, guns or recreational drugs or some service such as high interest loans (loan sharking), gambling or prostitution.--Joe]
