A Waterloo police officer who’s been accused of excessive force is now facing criticism for an illegal search in which he seized a loaded gun. The Iowa Court of Appeals ruled Wednesday that Mark Nissen’s warrantless vehicle search in 2014 was unreasonable. It overturned Ezekiel Phillips’ conviction for illegally carrying weapons, ruling the evidence is inadmissible. The city recently paid $170,000 to settle cases in which Nissen was accused of using excessive force.
