The children of those "cockroaches" have themselves to blame.
You do know that the USA created this problem, by installing and supporting dictators and terrorists in South America? If the USA hadn't destroyed those countries, they wouldn't have to come to the USA. (They have created the same situation in Europe by setting the Middle East in flames.) If the South American countries had been poor, but livable everybody would benefit. Instead of having illegal immigrants and a fortified border, you could have had seasonal workers. People would come when there were work in the USA and leave when there weren't. Because the illegality wouldn't be an issue, they wouldn't fear leaving the USA.
This is so fricken simple a child could figure it out. What is it with grown ups and pretending simple things are hard? Is it to make themselves look smart/less retarded? War equals refugees. Yet grown-ups (pretend they) couldn't connect the dots between war in Iraq and refugees. We are supposed to listen to what those idiots have to say! How are those people employed? I guess idiots hire fellow idiots.
