With all eyes on FIFA in the past days, I tend to wonder, why match fixing (or tournament fixing) is illegal in any sport.
I understand that fixing violates the rules of the governing body of a particular sport, but why does government and authorities need to get involved? By which right, do governments enforce internal rules of NGOs such as FIFA?
I understand that there is a deception involved here, but I don't understand how is that violating the law?
