reconstruct the following argument as induction by confirmation: The defendant insists that he didn't intend to shoot his wife. But the only conclusion that fits the facts s that he did intend to kill her. If he intended to do it, then he would have purchased the gun ahead of time, which he did. He would have taken her to a secluded place, which he did. He would have arranged an alibi, which he did. He would have had a motive, which he does. All the evidence you have heard supports the conclusion that he intended to kill his wife, and you should therefore find him guilty of first-degree murder
