Last month a Las Vegas jury acquitted two men — Ricky Lovelien of Montana and Steven Stewart of Idaho — for their parts in the 2014 armed standoff between the federal government and supporters of rancher Cliven Bundy. The jury found co-defendants Eric Parker and Scott Drexler not guilty of most charges but deadlocked on some. When it comes to trying the Bundys and their supporters, federal prosecutors now have a terrible record, winning just two convictions after two trials of six defendants in Nevada this year. Last fall, Bundy’s sons Ryan and Ammon Bundy and five others were acquitted for leading an armed takeover of Oregon’s Malheur National Wildlife Refuge in early 2016. The recent acquittals in the Nevada case raise big questions for prosecutors.
