There's an old saying in journalism: If your mother says she loves you, check it out.

It's a facetious way of saying: Trust no one, verify everything.

Yet some of the biggest, most respected media outlets in the country failed to perform their due diligence when it came to the Schapiro study's ridiculous claims about a nationwide child trafficking epidemic.

In an era defined by fast-paced blogging and doing more with less, reporters have precious little time to document the information they're regurgitating. This leaves readers vulnerable to pseudoscience and quackery.
