Ben Shapiro is set to speak at the UC Berkeley campus on Thursday, Sept. 14, 2017.

Police say the goal is to prevent a repeat of the violence that caused the cancellation of a speech by Milo Yiannopolis in February.

"We will be abiding by the Chancellor's clear statement that we will not tolerate violence," said Don Mogulof, a UC Berkeley spokesperson.

U.C. Berkeley says they expect to spend about $600,000 on security Thursday.

With all of the protests that take place across the Bay Area, SF public defenders are reminding residents of their legal rights if they're arrested.

"We can't turn a blind eye...and around the country," said Mugulof.

And this time, U.C. police may not stand down like they did when masked protesters shut down the Yiannpolis event.

In February, protesters set a fire and vandalized Zellerbach Hall through Chief Margo Bennett provided few details about exactly how things will be different, this time.

"I'm not going to specifically talk about tactical information, but certainly we have lessons learned from February 1st when we had that unprecedented attack on our campus," said Bennett.
