UPDATE 9/9: In the early morning, protesters locked down across the entrance of the Alameda County fairgrounds, preventing passage into the Urban Shield expo. Twenty-three people were arrested.

In July, the Santa Clara County Sheriff's Office withdrew its sponsorship of a "Bulletproof" street survival training course for law enforcement officers after community activists questioned whether the former "Bulletproof Warrior" class should be offered by the department. The seminar encourages police officers not to hesitate in the use of their weapons. The most famous alumnus of the two day training is Jeronimo Yanez, the St. Paul, Minnesota officer who shot and killed Philando Castile during a traffic stop.

Calibre Press, the private company that offers the training, had declined to reveal the new location, but Bay Area residents found out that "Bulletproof" took place on August 17 at 18 at the Family Community Church in San Jose.

Urban Shield, the controversial police militarization exposition and training, which features a large weapons expo and Bay-Area wide training drills on proto-military operations, gets underway in less than a month on September 8 in Pleasanton, California. The Stop Urban Shield Coalition is calling for a mass demonstration on September 9. Urban Shield is a public face of police militarization, while private companies like Calibre are private twins.
