To you and All who believe we could build a wall easily, and those who note there is a wall around the white house.
We couldn't build a wall around New Orleans in 9 months, but you think we can build a wall around our country in a year and a half?
This isn't some 4-foot rock wall. In order to be effective, it has to be better than the wall at the White House. That wall just stops people long enough for the guards to shoot them, and people get over that wall all the time.
The wall you would need to stop people without guards would be much harder than building a levee. It would be expensive, ugly, and take a long time and a lot of materials.
And it wouldn't stop immigrants from using hot air balloons. What, you say, they never used hot air balloons -- that's because they didn't have to.
No wall will help if you don't also put guards on, or use electronic monitoring. And if you do those things, you don't really need a wall if you have a dozen miles of desert.
People break out of prisons.
