It was initially supposed to be peaceful. But the protest at the California State University (CSU) Chancellor’s Office in Long Beach last year suddenly went awry. And the story of the melee—including a recognized photograph of protestors being arrested—became national news.

On November 15 of last year, a protest organized by the ReFund California Coalition turned heated when protestors faced university police after being ejected from a CSU Board of Trustees meeting.

During the debacle—in which two officers were injured, pepper spray was used by authorities and multiple students were arrested—a glass door shattered under the pressure of oncoming protestors, leading to the arrest of Seth Andrew Newmeyer, a 19-year-old from Palo Alto.

According to a video shown to the jury during his trial, it was Newmeyer’s persistent jerking of the door’s handles that caused the glass to shatter. It was this video that led to Newmeyer’s conviction of vandalism, along with being convicted of participation in an unlawful assembly.

“Mr. Newmeyer has every right to engage in a peaceful protest, but he does not have the right to destroy property or engage in violence,” said Assistant City Prosecutor Randy Fudge in a statement released to the press.

The sentencing hearing to be held Wednesday in Long Beach is expected to bring Newmeyer an order to pay $22,000 to replace the door.

“It is unfair for CSU students to pay for the doors when they were damaged by a small group of violent protestors,” said City Prosecutor Doug Haubert in the same press release.

Intriguingly, though Haubert stated that multiple violent protestors were involved, Newmeyer is the only protestor to face vandalism charges for the shattered door.
