text: The border wall is good as a symbol-- like the Statue of Liberty, but the opposite. But beyond that it is a waste of money. And that comes from border security experts working for the Trump campaign. Remember the campaign when Trump's experts explained Trump's wall as not a real wall, but a "wall" of electronic monitoring, ground penetrating radar to detect tunneling, drones, increased fleet of helicopters and boats (along the Rio Grande) increased number of special border patrol vehicles, and increased number of border patrol agents and facilities and roads along the border. They said these things would be more effective than a concrete wall and cost less. The wall they (Trump's experts) said would be extremely expensive because it would require road building to get construction material to the remote sites for the wall. The concrete and construction experts retained by Trump said the cost would be in the $20 Billion range-- same as a road from Seattle to Miami and back.
