He can't sue. If he is an illegal alien, and as he is now in the public spotlight, he will be deported. Authorities cannot knowingly let an illegal stay once he's been uncovered.
HAHAHA You can't be serious. They let uncovered illegals stay all the time. In the summer of 2012 obozo announced his amnesty plan for millions of illegal "dreamers". The law still says they can't stay but obozo said "guess what. I'm not gonna enforce the law".
Denver, CO is one of the growing number of "sanctuary cities" that allow and even welcome illegals to stay.
Colorado tax payers feed them; house them; provide medical coverage for them and their "anchor babies"; and bend over backwards to make them feel more like welcome citizens than legal Americans.
Right across the street from me is a small, 4 unit apartment complex full of Mexicans who know little or no English. There must be 25 cars parked there. It's massively over-crowded and the trash that blows from the property proves that they don't give a damn about their neighbors or the trashy property they inhabit. They've brought their culture with them which is turning out to be a real blight on our society.
I'm not surprised that the illegal in the OP is suing for having his life saved. They have an entitlement mentality. And why shouldn't he considering the fact that he gets everything else for free.
