Final answer:
The rumor about the destruction of the chop shop is not specific in the context provided. Information given relates to the Chicano Moratorium and police violence during a protest in Los Angeles, leading to the death of journalist Ruben Salazar.
Step-by-step explanation:
The rumor about how the chop shop was destroyed is not directly addressed in the provided information. However, the context suggests a historical event rather than a crime or a fire related to an auto supply store. Specifically, the mention of Chicano Moratorium and the tragic death of journalist Ruben Salazar during the police disruption of a peaceful protest in Los Angeles in August 1970 is highlighted.
While the rumored destruction of the chop shop could relate to social unrest or police action, similar to the events of the Chicano Moratorium where police used excessive force under the pretext of searching for a liquor store bandit, leading to violence and casualties, there is no clear information linking this to the shop's destruction. Thus, the exact nature of the rumor is not defined.
