From the piece, called "The Thin Blue (Digital) Line":
A balance must be achieved here. One could argue that we have a very strong incentive to know as much as we possibly can about those we pay to protect us. So, we should want members of law enforcement to be online as much as is practical, so long as it doesn’t interfere with their duties or compromise loved ones. A policy, if too-broadly drawn, may have a chilling effect at precisely the time when citizens desire more transparency from their government.
