Good morning.

Today’s introduction comes from Thomas Fuller, our San Francisco bureau chief.

Free speech is expensive. That was one takeaway from the University of California, Berkeley campus on Thursday as the Berkeley College Republicans hosted Ben Shapiro, the latest in a line of conservative speakers to roil the flagship campus. The university estimated it spent $600,000 on security for Mr. Shapiro’s visit, not a pittance for an institution that has struggled financially in recent years.

Dan Mogulof, a spokesman for the university, said a similar amount was spent in April to secure the campus during the planned visit, later canceled, of Ann Coulter, the right-wing pundit.

Like Ms. Coulter and Milo Yiannopoulos, another right-wing provocateur whose visit to the campus sparked outrage in February, Mr. Shapiro has made a career out of poking fun of liberal beliefs and casting college campuses as bastions of intellectual intolerance. The 1,000 tickets to see Mr. Shapiro’s Thursday show, titled “Say No To Campus Thuggery,” sold out in less than an hour.
