Ghanaian "Juju Man" Offers To help FBI

A Ghanaian juju man (witch doctor) is hoping to travel to the US to help catch the serial sniper. The D.C.-area sniper, who is nameless and has killed nine people, as of this writing, has a $500,000 reward on his head.

Sumsum Bafour, famous juju man in Swedru, i.e. according to him, has promised to present a "psychic profile" of the sniper to the FBI once he gets to USA.

A mail from Bafour (unedited):

"Mr. Akoto,
(.... section of mail removed)
if you help me obtain a Visa and buy my ticket to USA, I promise to catch the sniper and share the reward with you. I am going to carry out a ceremony to get him to come to me. I have been able to catch many criminals in Accra, Swedru and Koforidua with the help of my mystical powers. Send me a ticket and get me a visa and we’ll share whatever is the reward.
Don’t let me down”

Sumsum,
why don't you use your powers to get a ticket & visa?
