Let me outline the premise that sits at the bottom of my argument:

Michael approaches you, and says, "I'm giving you the Roth hit. When Roth gets off the plane, he'll immediately be surrounded by armed customs men and half the FBI. You'll dress up as a reporter so you can get close to him, and kill him." Unspoken words: "It is obvious to me and you that there is absolutely no chance that you will make it out of that airport. On the day of the hit, your life is over. After you shoot Roth, only a miracle will prevent you from being shot dead by the FBI."

When someone approaches you with this order, what are they saying?
