From Philly.com:

PHILADELPHIA could be facing a class-action lawsuit on behalf of gun owners who say the city violated their privacy by publishing their personal information and launching an interactive Web map that included clickable icons of revolvers over their homes.

Attorney Joshua Prince filed a motion this week in Common Pleas Court, requesting that the suit be sealed to avoid revealing the names of his five clients - and potentially hundreds of others if the case is granted class-action status.
