Magister, the fact that Bo's family may have been aware of Neil Heywood's connections would challenge the motive for the Brit's murder. Had there been a plan to dethrown/discredit Xi Jingping, it'd have been pretty uneasy for Bo. It was hard to believe the Brit came to the city to blackmail or get laid. Also, it was suspicious that British government laid low in the case when no autopsy was pefromed there.
Justice to all
