WHY ARE SOME PEOPLE UNDOCUMENTED? THAT IS JUST A TERM LEFTIES USE INSTEAD OF ILLEGAL. MANY ARE DECENT PEOPLE FOR CRIMINALS, THEY WILL WORK, USUALLY UNDER A FAKE NAME AND SOCIAL SECURITY NUMBERS, RUN WELFARE SCAMS AND OTHER NON VIOLENT CRIMES. OTHERS ARE HARDENED CRIMINALS AND OFFER THIS WORLD NOTHING BUT MISERY.
