Take a look at the concrete barrier Israel built. I would estimate its height to be at least 35 feet. Few if any Mexicans would attempt to scale that monster.

There are only a few miles of wall like that. The rest is fence, and even that only covers a border that is a fraction of ours with Mexico. If you want to have less illegal aliens in the country, don't waste your time talking about walls.
