FILE - This undated file photo provided by the Montana Department of Corrections shows Curt James Brockway. Montana authorities have charged Brockway with assault on a minor after a witness said he threw a 13-year-old boy to the ground because the boy didn't remove his hat during the national anthem at a rodeo.
