Sir: In asking, "How do you explain to your children that it is
okay to pick and choose those laws that you obey and those you
don't?", Graham Evans (Letters, 30 October) confuses legal
imperatives with moral ones.

History is littered with unjust or misconceived laws. It is not
just okay to distinguish between those laws which are right and
those which are wrong, it is our responsibility. When - as in the
case of cannabis prohibition - the law is merely an ass, it
should be treated as such.
