Where a defendant convicted of distributing cocaine challenged the admission of testimony from a federal agent, arguing that because the agent gave lay testimony about his personal knowledge of the investigation, it was then error to admit his expert testimony interpreting drug jargon, the admission was not an abuse of discretion because the District Court and counsel took appropriate measures to minimize the problems that could arise from the dual-role testimony. Judgment is affirmed.
