For many people, especially those of certain age, life is lived in the social media spotlight. Twitter, Facebook, and Instagram have become the popular way to communicate. Ordinary citizens are not the only people who use social media. User beware: If your friends can see your posting, so can law enforcement. A recent survey of agencies throughout the country found that over 80% of those agencies use social media in their criminal investigations. Lawyers also routinely use it to discover evidence about litigants, witnesses and even jurors.
