I've been coming to Stanford events for years and I usually take a short video clip or 2 to remember the event years layer .. Plus people seem to enjoy them .. I understand if Stanford doesn't want people to live stream or tape the entire event ( which I would never do nor want to do) but short clips have always been a basic public legal right at public events (even if they are on 'private property ' such as a stadium, private school, etc. for parents, fans, journalists etc.
