I stole the following from
http://www.datanation.com/fallacies/equiv.htm
(i) Criminal actions are illegal, and all murder trials are
criminal actions, thus all murder trials are illegal. (Here the
term "criminal actions" is used with two different meanings.
Example borrowed from Copi.)
(ii) The sign said "fine for parking here", and since it was
fine, I parked there.
(iii) All child-murderers are inhuman, thus, no child-
murderer is human. (From Barker, p. 164; this is called
"illicit obversion")
(iv) A plane is a carpenter's tool, and the Boeing 737 is a
plane, hence the Boeing 737 is a carpenter's tool.
