Argument: Tunnels will be dug to bi-pass a 700-mile fence
- GlobalSecurity.org 5/17/06 - "Tunnel passages across an international border into the United States have become a real problem. There are 40 such tunnels that have been discovered since 9/11, and the great bulk of them are on the southern border. Large-scale smuggling of drugs, weapons, and immigrants takes place today through these tunnels. One tunnel running from San Diego to Tijuana was marked by inordinate sophistication. It was a half mile long. It went 60 to 80 feet deep, 8 feet tall. It had a concrete floor. It was wired for electricity. It had drainage. At one end, 300 pounds of marijuana were found, and at the other end, 300 pounds of marijuana."
