A federal appeals court Wednesday ruled that Border Patrol agents cannot cut razor wire that Texas installed on the U.S.-Mexico border in the town of Eagle Pass, which has become the center of the state's aggressive measures to curb migrant crossings.

The U.S. Court of Appeals for the Fifth Circuit rejected Texas Gov. Greg Abbott’s request to reverse a lower court’s finding that the floating barriers were illegal.

Texas authorities have placed over 100 miles of razor wire along the southern border. Does razor wire really keep migrants from entering the country illegally, and is it worth the cost?
