Excerpt:Â Nearly 50 million "Americans" lack health care insurance. At least, director Michael Moore makes this claim in "Sicko," his new "documentary" about America's supposedly awful health care system.Nearly 50 million Americans without health care insurance? For what it's worth, the Centers for Disease Control puts the number of uninsured at 43.6 million, and the Census Bureau at 44.8 million.

Many emergency rooms, by law, provide medical care to anyone who walks in, whether an illegal or legal resident of this country.
