I think the Churchill episode raise two issues that don't
involve free speech: (1) If the things listed on his
curriculum vitae to the University are false, this is
clearly fraudulent. (2) Most schools should intensively
reevaluate ways that a tenured professor can be dismissed.
As it now stands, to dismiss a tenured professor at
Colorado involves seven enormously complicated (and
expensive!) steps. When a tenured faculty member should
clearly be dismissed, too often the school feels that the
"game isn't worth the candle". The result is that ALL
concerned are worse off -- students, tax-payers, and
the quality of the general faculty.
All very true and well stated, although I would suggest that in addition to the issue of expense, there is of course the issue of ideology which trumps all on college campuses these days. You aren't going to get the administration of public colleges and universities to dismiss an instructor for virulent anti-American comments these days because those comments are going to be very much in line with the belief system of the college administration, period.
