What does it mean to be an expert on deaths in Amazon Warehouses? She was a Union Organizer. Presumably, unions are most interested in working conditions and pay. She spoke out about the working conditions that she feels caused the death. This seems inline with what a union organizer would do, but more importantly, who the hell do you think is going to be more authoritative on this than a union organizer? What credentials do you feel she is lacking and who has the credentials such that you would be willing to defer to them as an expert?
