The left's turn to condemn lying "in a good cause"

Some on the Catholic left have praised those of us who have criticized lying as a tactic to advance the pro-life cause.  They now have an opportunity to earn our reciprocal praise.  Some physicians supporting protesting teachers and other state workers in Madison, Wisconsin are falsely attesting that protestors have legitimate medical excuses for failing to report for work.  This is out and out lying.  It is not transformed into something other than lying by the belief, even if true, that the cause in which the lying is being done is just and good.  I do hope we will hear clear condemnations of these tactics by people, especially Catholics, who support the protestors and their goals.
