An Iowa man who flew a U.S. flag upside down under a Chinese flag to protest future placement of an oil pipeline near his home has been charged with desecrating the American banner.

Homer Martz told The Messenger the pipeline will be placed without his consent next to the well supplying his Calhoun County home south of Somers. The town is about 20 miles southwest of Fort Dodge.

Martz said he put the flag up to protest what he said was a lack of due process after he wasn't notified at first about the pipeline.

that flag burning and other forms of damage are constitutionally protected free speech.

The pipeline route starts in North Dakota and runs through South Dakota and Iowa before ending in Illinois.
