Laboratory experiments forcefully demonstrate that crowding causes aggression and killing, but you don't have to go to a lab to see the same thing happening on American streets.
The United States is far past the population mark that fosters quality life, ample jobs and the goal of the American dream.
Now introduce illegal immigration and the problem is compounded many fold because these immigrants have not sworn allegiance to the United States, most don't pay taxes, many send money earned here to their homeland but use the services of this country. This, then, is a lose/lose situation for America and an insult to those that "went through the system" to become a loyal U.S. citizen.
