According to the San Bernardino Police Department, uniformed officers from a specialized unit were investigating complaints from neighbors about an illegal gambling facility on Saturday at about 8 p.m.
Security camera footage showed two officers driving past the facility in an unmarked vehicle before stopping their car just a few yards from the parking lot where the gambling facility was located.
Robert Adams, 23 could be seen talking to someone before walking in the direction of the officers' vehicle. As he approached the car, two officers jumped out with their guns drawn shortly before Adams began to run towards a nearby wall.
