Offensive speech and unwilling listeners

[Frank Cross]

I can't say that I've decided about the use of these materials in class, 
whether pornography or other offensive matters.  But I'm not convinced that 
they are necessary.  One can teach criminal law without committing a crime 
in class.

The materials do seem like relevant facts that law students should come to 
grips with.  But time and place and context are also relevant facts.  I'm 
not sure that viewing obscenity in class is the same as viewing it in 
private.  So showing obscene materials in class doesn't directly illuminate 
the question of whether it should be regulated for private consumption.
