[Marcus Marulus]

Making lying in general a crime is impossible. There are many cases in which you must lie in order to survive, for example, when you are concealing some information from your enemy or from the oppressive and unjust government. That lying should be avoided and not practiced and that sicerity should be encouraged, is part of a sound moral teaching. So lying should be avoided in all cases, except in the two mentioned above.

And hypocrisy - which is nothing else that lying turned into a system - is already a crime, in the moral sense, although not in the judicial one. Maybe that should be banned and /or made a crime.
