Rozeboom then wants to maintain that the belief in question will then have to be justified if one is to have a case of knowledge. So (3) needs to be replaced by something like: (3*) A is justified in being completely certain that p is the case. Next, Rozeboom suggests that a person, A, is not justified in being completely certain about the truth of p on the basis of some body of evidence, E, unless, given E, p couldn't possibly be false. But if this is right, then, in the first of Gettier's examples, Smith would not be justified in being completely certain that Jones would get the job, for the evidence that Smith had was perfectly compatible with Jones's not getting the job - as in fact turned out to be the case. As a consequence, neither would Smith have been justified in being completely certain that someone with ten coins in his pocket would get the job.
