The superintendent of schools for Oxnard announced that students would be treated as truants, etc., etc., and that the walkout was a bad idea because it couldn't change the election results.
(Follows quote from Ventura newspaper)
However, Charles Weis, Ventura County superintendent of schools, noted
that the proposition did not pass in Oxnard, Fillmore or Santa Paula. The
three cities have the county's highest proportion of Latino residents.
"What this proposition was, was people voting for other people's
children's education," he said. "If anything, I hope these students learn
that if they want to affect their future they need to get registered, get
involved with campaigning and get out and vote."
... but not, presumaly, take any kind of direct action.
There were walkouts at high schools in Los Angeles and Orange counties as well (and probably other places we don't know about yet).
