Letter-writer Keith Vacula (“No walls,” Feb 17, TribLIVE) is sadly mistaken on there not being a wall between North and South Korea. They may not have a “wall,” but they have a mine field in a wide no-man zone.
Also, the Vatican has a wall, as does Jerusalem. Tthe Roman Empire had walls, and so on.
Walls have been used throughout history to protect the inhabitants on the inside, and considering the drugs, human trafficking and illegal activity that is occurring around our so-called borders, we need this protection. Wake up, America — and that includes Vacula.
