To say that the FBI had its work cut out for it after 9/11 is an understatement. As part of its anti-terrorism efforts, the agency cozied up to telecom companies, like Verizon and AT&T. The relationship was so tight that some telecom employees actually had offices at the FBI.

This convenient arrangement paved the way for FBI agents to ultimately hand post-it notes with phone numbers to their telecom pals to find out if those accounts were worth investigating. It's the sort of stuff that makes privacy advocates shudder. And it's what Jennifer Lynch, staff attorney at the Electronic Frontier Foundation, says we don't want to see repeated now that the FBI has created a new surveillance unit.

The recently established Domestic Communications Assistance Center (DCAC) will develop new ways to eavesdrop on our communications. The FBI has been falling behind when it comes to this particular sector of snooping since the 1980s and early 1990s, when landlines were our primary method of communicating. If you're using a traditional phone, the FBI has very few problems keeping tabs on you. Today however, we use Skype, we tweet, send messages on Facebook, and hangout on Google to communicate with our friends, family, and associates. And the FBI wants to make sure it can detect illegal activity taking place on those channels, too.

Right now, Lynch and her colleagues at EFF are finding there's a scant amount of information about this new department of the FBI. Learn what action EFF plans to take in my report above
