These days, so much depends upon language. One person's "civil war" is another's "random violence." Someone's "unlawful wiretapping" is someone else's "terrorist surveillance."
In that sense, whether you use "illegal aliens" or "undocumented residents" partly depends on how you view immigration. But whatever your political attitude, if you think that every illegal/undocumented came into the United States guided by a coyote, then think again.
