Some inconsistent messages are coming out of my alma mater:

Northwestern University’s president said Thursday that he is “troubled and disappointed” that a psychology professor allowed a couple to engage in a sex act involving a motorized sex toy in front of dozens of students, and he is calling for an investigation.
Hours after accounts of the Feb. 21 class appeared in local newspapers — including the university’s defense of Professor John Michael Bailey’s decision to allow students to witness the act — Northwestern President Morton Schapiro strongly criticized the lecturer.
“I feel it represented extremely poor judgment on the part of our faculty member,” Schapiro said a statement issued by the Evanston university.
. . .
Evanston police say it will be up to the school to determine if the demonstration violated any local ordinances.
The guest lecturer asked the students if they were “ready for a live sex show,” student Justin Smith told the Chicago Tribune.
