No I am not saying illegal aliens are hitmen or are like hitmen.  

I am saying that words matter and PC terms like "undocumented worker" inherently and intentionally confuse the issues.  

First off, these folks may or may not be "workers."  To Nashty's credit he used "person" instead of "worker." 

Secondly, being "undocumented" downplays matters to makes it appear like they are just missing inconsequential ministerial steps that dont really matter (akin to someone from this country being asked to stop by HR to fill out some paperwork).  That grossly understates the fundamental problem that they are breaking the law and are present in the country in a manner contrary to law.  Also they are cutting in line ahead of those doing it the right way.

"Illegal alien" actually captures it much better.  The presence of these persons is illegal.  "Alien" doesn't suggest they are E.T., but is used in the dictionary sense of "belonging to a foreign country or nation" or "a foreigner, especially one who is not a naturalized citizen of the country where they are living."
