John B. Kearney, a Ballard Spahr partner who’s practiced law for more than 30 years, was a speaker at the recent Camden County Bar Association seminar about social media and “electronic discovery.” “People don’t realize how many different places information is stored,” Mr. Kearney said. “There’s nothing that says a lawyer can’t access the public information. … It’s as if you wrote something on a wall, and we saw it. What you can’t do is misrepresent who you are, or who you’re representing, in order to gain access to that private area of Facebook.”
