Describe some wartime attacks on civil liberties (WWI).

The main attack on civil liberties in the US during WWI
was the passage and enforcement of the Espionage and Sedition Acts.  These acts made it
illegal, in effect, to criticize government leaders and/or the war effort.  It also
allowed, for example, the postmaster-general of the US to bar anything from the mail
that would violate the act.  This law was used to imprison Eugene V. Debs for speaking
out against the draft.  The law was also used to obtain more than 1,000 convictions
against people like Socialists.

Another possible candidate
for an attack on civil liberties was the attack on all things German.  For example, the
teaching of German in public schools essentially disappeared during the war.  This is,
however, a less clear-cut case of infringement on civil liberties because there is no
constitutional guarantee that any language can be taught in
schools.
