A federal jury in Las Vegas declined to convict four men of any crimes for their participation in the 2014 armed standoff near the Bundy ranch in Bunkerville, Nev.
During that conflict, ranchers and militia members blocked federal officers from confiscating livestock owned by the Nevada cattleman Cliven Bundy.
On Tuesday, jurors acquitted the defendants Richard R. Lovelien and Steven A. Stewart of all charges and O. Scott Drexler and Eric J. Parker on most counts against them.
Jurors could not reach a decision on two charges against Mr. Drexler and four charges for Mr. Parker, all related to an alleged assault on a federal officer while carrying a firearm. The United States District Attorney’s office in Nevada issued a statement on Tuesday saying that prosecutors had not decided if they would retry the men on those charges.
