Brooks County is a county located in the U.S. state of Texas. As of the 2010 census, the population was 7,223. Its county seat is Falfurrias. The county is named for James Abijah Brooks, a Texas Ranger and legislator. The county faces a range of challenges due to immigration issues. Sheriff's deputies are often the only line of defense for residents whose homes are broken into for food and water and to respond to violent crimes committed by some immigrants, but the increase in these challenges has left the sheriffs department to contend with budgetary limitations.
