The Santa Clara County District Attorney’s Office recently charged a dozen people with breaking into a Stanford University campus building, barricading themselves inside and vandalizing administrative offices during a destructive anti-Israel protest at the elite liberal Northern California school last June. 

Prosecutors said the 12 masked people, whose ages ranged from 19 to 32, allegedly “broke windows and furniture, splashed fake blood and disabled security cameras.” 

There was allegedly hundreds of thousands of dollars worth of damage, according to a news release from the district attorney’s office.

Protesters’ backpacks were recovered inside the building and included forcible entry tools such as an electric grinder, hammers, crowbars, chisels, screwdrivers, goggles, numerous straps and cables.  

Cellphones recovered from those who were arrested showed encrypted text messages and links to detailed operational plans, according to officials. 

Prosecutors allege the communication “indicated the suspects met on multiple occasions, days in advance, to conspire to take over the building,” according to the release.

“Dissent is American. Vandalism is criminal,” said District Attorney Jeff Rosen. “There is a bright line between making a point and committing a crime. These defendants crossed the line into criminality when they broke into those offices, barricaded themselves inside, and started a calculated plan of destruction.”

A “DO-IT-YOURSELF OCCUPATION GUIDE” shared in the communication stated, “Vandalism? Occupying a space removes the space from the capitalist landscape. A group may decide it is better to destroy or vandalize a space than to return it to its usual role in good condition. The role of vandalism may be different in each situation, but it should not be disowned outright.”

A student journalist, who had embedded with the protesters but did not participate in the vandalism, was not charged.
