Boxing's connection to terrorism

The 9th Marquess of Queensberry is well known for having developed the rules under which modern boxing is conducted. His great-grandson, David Douglas, is the current holder of the title. Douglas has an illegitimate son, Ambrose Jonathan Carey, whose half-sister Caroline married the late Salem bin Laden, head of the global Bin Laden family corporation. Salem was a half-brother and cousin (not sure how that works) of the infamous Osama bin Laden.
