Iranian metallurgist is doing electron microscopy at Case Western Reserve University, in Cleveland. The feds think he’s also passing secrets back to Iran (about how its navy could better resist saltwater corrosion), so they seek a warrant based on the metallurgist’s visa application, which suspiciously never mentioned Cleveland. Enough for probable cause? Sixth Circuit: It matters not. A magistrate gave them a warrant, so even if it was legally defective, the feds were entitled to rely on it in good faith.
