Scott Tucker (letter, March 10) asserts that the students and professors who participated in the recent class walkouts to protest the idea of war in Iraq "shunned higher education." I beg to differ. The students were learning about one of our country's proudest traditions -- principled dissent -- in a hands-on way. It's not like they were cutting school to go goof off. Not all education takes place in classrooms. Do the people who are complaining about these demonstrations complain when students take field trips?
