Cell Phone Privacy Katie Couric: How many times have you sent a private text message using a phone, pager, BlackBerry, or desktop computer supplied by your employer? Today, the Supreme Court said it will consider whether such text messages really are private. Here's Nancy Cordes. NANCY CORDES (VOICEOVER): It's a case that could have implications for anyone who emails, texts, or even tweets from work. Just how private are those private messages? MARC ROTENBURG (DIRECTOR OF ELECTRONIC PRIVACY INFORMATION CENTER):This case has the potential to be groundbreaking. NANCY CORDES (VOICEOVER): The case pits a SWAT team sergeant from Ontario, California, against his police chief and a local wireless company, which provided the chief with transcripts of text messages sent from the sergeant's police-issue pager. Some of the text messages were sexually explicit notes to his girlfriend. Lower courts have split over whether the sergeant's privacy was violated or whether his chief had every right to read communications sent from an office device. I think there's no question that the lines between the workplace and home have become increasingly blurred. We use email accounts for both work-related matters and personal matters. NANCY CORDES (VOICEOVER): And the rules are often blurry, too. The Ontario Police Department's written policy, for instance, warned officers that, quote, "The use of these tools for personal benefit is a significant violation." Now the Supreme Court has agreed to decide once and for all whether workers have any right to privacy when they're writing or texting from the office. Nancy Cordes, CBS News, Washington.
