As the philosopher/baseball player Yogi Berra once (supposedly) said, it’s deja vu all over again. Student protesters are occupying the campuses of famed universities across the country. In New York, Columbia University protesters occupied administrative offices in Hamilton Hall and were cleared out by police, exactly 56 years to the day after student protesters occupied and were thrown out of that building in 1968.

Back then it was famously reported that protester Mark Rudd sat at president Grayson Kirk’s desk smoking his cigars. It’s not clear whether protesters reached president Manouche Shafik’s office, but it seems unlikely that any humidor there contains tobacco.
