Criminal law has to do with relations between the misbehaving individual and his government...Criminal law establishes rules of conduct; their breach, if prosecuted and conviction follows, results in punishment.
The ethical practices of lawyers are probably no worse than those of other professions. Lawyers bring some of the trouble on by claiming in a sanctimonious way that they are interested only in justice, not power or wealth. They also suffer guilt by association. Their clients are often people in trouble. Saints need no lawyers: gangsters do.
Law..is too important to be left to the lawyers.
Ideas about the scope and meaning of freedom of speech do expand and contract with the times. At the moment, we live in an age that is very permissive, both legally and socially, on a wide range of subjects from Karl Marx to kinky sex. This has not always been the case. Things that even children freely see and read and hear today -- writings, pictures, words -- would have been banned as just plain obscene, even for adults, as recently as the middle of the twentieth century.
