Just call them CRIMINALS ...
They broke several laws getting here. They are breaking several laws staying here. Then, a large percentage break even MORE unrelated laws.
Isn't someone who breaks the law (not to mention several) a CRIMINAL and supposed to be a FUGITIVE FROM JUSTICE?
Aren't there laws against aiding and abetting FUGITIVES?
So ... can't we go after the people who hire them, rent to them, assist them ... and the Government, State, City &/or Towns who assist them in ANY way for "Aiding and Abetting a Fugitive" (or several)?
