“Adios, America: The Left’s Plan to Turn Our Country into a Third World Hellhole” by Ann Coulter –
“We’ll talk about legalization as soon as it’s as hard to get into the United States as it used to be to get out of East Germany.”

A quick google search landed me on a History Channel article on the Berlin Wall where I found the following paragraphs:
“The construction of the Berlin Wall did stop the flood of refugees from East to West, and it did defuse the crisis over Berlin. (Though he was not happy about it, President Kennedy conceded that “a wall is a hell of a lot better than a war.”) Over time, East German officials replaced the makeshift wall with one that was sturdier and more difficult to scale. A 12-foot-tall, 4-foot-wide mass of reinforced concrete was topped with an enormous pipe that made climbing over nearly impossible. Behind the wall on the East German side was a so-called “Death Strip”: a gauntlet of soft sand (to show footprints), floodlights, vicious dogs, trip-wire machine guns and patrolling soldiers with orders to shoot escapees on sight.
In all, at least 171 people were killed trying to get over, under or around the Berlin Wall. Escape from East Germany was not impossible, however: From 1961 until the wall came down in 1989, more than 5,000 East Germans (including some 600 border guards) managed to cross the border by jumping out of windows adjacent to the wall, climbing over the barbed wire, flying in hot air balloons, crawling through the sewers and driving through unfortified parts of the wall at high speeds.”
