However, there were many bombings in California during this time period. Also, the explosives used in the two attacks were not the same. The offices of standard oil were the targets of anti-war protesters the same day as the bombing. Standard Oil of California was also known as the Chevron Oil Company. Moreover, the Chicano Liberation Army claimed credit for the incident in a tape recording sent to the Los Angeles Free Press. The CLF stated that they were "fed up with our people being treated like dogs." However, authorities could not confirm if the CLF actually committed the attack.
