How many people were shot by the Mexican police officers? [originaltext] Four

Fourteen Mexican police officers have been charged with attempted murder over the shooting of two US government officials and a Mexican navy officer. In August, gunmen opened fire on a car with diplomatic license plates. There were two CIA agents inside and a member of Mexican marines. Since the investigation unfolded under pressure from Washington, it became clear that the gunmen were in fact federal police officers. The government suggested that the officers were in league with the country’s violent drug groups and that the attack was in some way related to the cooperation between the United States and Mexico in a fight against drug trafficking.
