JACKSON, Mississippi (AP) -- Google is scheduled to face off with Mississippi's attorney general Friday.
The Internet giant will ask U.S. District Judge Henry T. Wingate to block an investigation by Attorney General Jim Hood into the company.
Hood is looking into whether Google was facilitating illegal activity through its auto complete service, which automatically fills in words for the user, such as "how to buy oxycodone."
The closely-watched case has Google and computer industry groups telling the judge that a 1996 federal law protects Internet companies from being held accountable for what third parties say.
Google argues it's immune from much or all of Hood's inquiries under a 1996 federal law.
Hood says Google has jumped the gun on its objections because he doesn't know what his inquiry will find.
