What a crock of shit. It's a very simple concept, if an illegal alien hadn't entered the country they wouldn't have the ability to commit a crime here. And these whack-a-do idiots that put these studies together never include the crime they committed just to get here, or the identity theft, fake documents they buy and other crime they commit to work here. In fact every day they remain and go to work they are committing another crime, as are the people that hire them. So shove your faux studies, they are meaningless.

So where do the majority of illegal aliens come from?
Virtually every country in the world. 40% through the southern border.
