^3. Of course, the mere fact that an inference can be assigned in favor of the government's case does not mean that the evidence on a disputed crime element is sufficientthe inference, along with other evidence, must demonstrate that a reasonable jury could find the element beyond a reasonable doubt, i.e., "'[a] reasonable inference is one that is supported by a chain of logic, rather than mere speculation dressed up in the guise of evidence.'"
