Here we have a 10 page thread 186 post and not one person showing where a wall has not worked. OK, that's not total accurate, if you go back to when the Romans ruled the world and in a war setting...or to WW2 and a War setting, Patton said a Wall would not stop him. But other than during Roman times and when a Army has tanks, and bombs....

NOT ONE EXAMPLE

On the other hand its been shown, where ever people put walls...the wall does exactly what it was put up for. It doesn't matter if the wall was around a persons home or between two borders. They work but the sky screamers wont let the facts control what they think . But even then, if they were being honest....

most of those in government and those posting in topics like this one knows the real truth. Walls work!
