“You build a fence....they will build tunnels.”
A foolish objection.
There are security fences all over the country. Somehow the prospect of tunnels hasn’t deterred people from putting up fences.
WOOOHOOO Cain nailed that one. Blame the administration!
The difference being that both sides of the fence are inside the country and can be monitored. We have no control over the other side of a border fence. Today the illegals approach the border fence essentially unhindered and uninterrupted. Wherever there is fence along the border now, there are also tunnels under it. Some of the tunnels are reinforced with brace supports, have air piped in, and electricity.
Wake up. A fence is only a small part of the answer. By itself, it is worthless.
