Homeland Security agent in Detroit uses his position as a federal officer to illegally detain someone for personal purposes. Yikes. And then at trial for that, prosecutors threaten him with impeachment evidence of his (alleged) lying about other misconduct on the job, which he committed as a favor for a woman he was sleeping with. More yikes. He doesn’t want to get impeached, so he chooses not to testify. Sixth Circuit: The prosecutors could do that. Conviction stands.
