In my opinion, the timescale for such an assassination is merely during the next few years. Such a person cannot be allowed to grow old before they are killed ; they must leave in the flush of youth, so they are immortalized in our consciences, a la Monroe, Dean, Lennon, Diana etc.
Beckham is a prime candidate for assassination and I believe that he will probably be killed before the age of 35, the age when I expect him to retire from playing football. His death will reverberate around the world, and he will become a martyr. For what cause, I truly cannot say. Needless to say, he will not deserve such adulation, but then he does not deserve the fame he enjoys at present.
If I am proven wrong on this point, forgive me. I just have a feeling that this man will die prematurely.
