Does
 the U.S. government read your email? It's a simple question, but 
apparently there's no simple answer. And the Justice Department and the 
Internal Revenue Service are reluctant to say anything on the topic.
In
 March, the American Civil Liberties Union caused a nationwide stir when
 the advocacy group released the results of its year-long investigation 
into law enforcement use of cellphone tracking data. After issuing 
hundreds of Freedom of Information Act requests, the ACLU learned that 
many local police departments around the country routinely pay mobile 
phone network operators a small fee to get detailed records of historic 
cell phone location information. The data tell cops not just where a 
suspect might have been at a given moment, but also create the 
possibility of retracing someone's whereabouts for months. In most 
cases, law enforcement obtains the data without applying for a search 
warrant; generally, subpoenas are issued instead, which require law 
enforcement to meet a lower legal standard.
ACLU lawyer Catherine Crump, who ran the cellphone location data 
investigation, is at it again. This time, she has filed similar Freedom 
of Information Act requests with several federal agencies, asking about 
their policies and legal processes for reading Internet users' emails.
"It's
 high time we know what's going on," Crump told msnbc.com. "It's been 
clear since the 1870s that the government needs a warrant to read postal
 mail. There's no good reason email should be treated differently."
There are hints that it is being treated differently, however. In a 
landmark 2010 case, United States v. Warshak, government investigators 
acknowledged that they read 27,000 emails without obtaining a search 
warrant, violating both the suspect's privacy and the privacy of 
everyone who communicated with the suspect, according to Crump.
Evidence obtained during that email search was thrown out on appeal by the 6
th U.S. Circuit Court of Appeals, but that ruling applies only to four U.S. states.
The case opened a window into what Crump fears is a widespread practice.
In
 the aftermath of the Warshak case, the Internal Revenue Service told 
its investigators that they should not try to obtain emails without a 
court order, but in doing so it hinted that other warrantless email 
searches had been conducted in the past.
For now, hints are all we
 have. Crump's Freedom of Information Act requests -- filed in February 
with the FBI, the IRS, the Justice Department's Office of Legal Counsel 
and other agencies -- were largely ignored, she says. So on June 14, she
 filed a lawsuit in the Southern District of New York in an attempt to 
force the agencies to comply.
"Four months have passed and I haven't gotten a single document," she said. "The American people have a right to know."
The
 federal agencies have until July 19 to reply to the lawsuit. The FBI is
 not included in the lawsuit because it replied recently denying Crump's
 request, saying it was too broad. The ACLU is appealing that 
determination through a different legal procedure.
Justice 
Department spokesman Charles Miller directed all questions about the 
matter to the agency's New York office. A spokeswoman for that office, 
Ellen Davis, said she couldn't discuss it.
"We do not comment on ongoing litigation," Davis said in an email.
Julianne Breitbeil, a spokeswoman for the IRS, said federal privacy laws prevent the agency from discussing the lawsuit.
The
 Justice Department and the Obama administration had a chance to settle 
the issue in April 2011, during a Senate hearing on the Electronic 
Communications Privacy Act. Instead, officials with both the Commerce 
and Justice departments failed to provide any clarity. Instead, a 
Justice Department official argued against extending Fourth Amendment 
protections -- specifically strict warrant requirements -- to email, 
saying that doing so would hinder investigations.
"Congress should
 consider carefully the adverse impact on criminal as well as national 
security investigations if a probable-cause warrant were the only means 
to obtain such stored communications," James Baker, associate deputy 
attorney general, 
testified at the hearing.
Crump interpreted the testimony as indicating that warrantless email searches by federal agents are routine.
"It
 was disappointing when the Obama administration refused to commit one 
way or the other to obtaining a warrant," she said. "It leads me to 
suspect the federal government isn't getting warrants."
A 
critical element of the email issue is a debate about whether the Fourth
 Amendment requires the government to get warrant based on probable 
cause in order to read a suspect’s email. To get a warrant, the 
government must appear before a judge, and convincingly argue that 
inspection a suspect’s email will probably turn up evidence of a crime.
"The
 warrant and probable cause requirement safeguard Americans' privacy in 
two important ways. Having to go to a judge means there is someone 
involved whose job it is to look out for the target's rights. And having
 to demonstrate probable cause will reduce the chances that innocent 
people have their communications read," Crump said.
The 
distinction is also important as the U.S. government plunges headlong 
into new high-tech surveillance technologies, such as its massive new 
million-square-foot "Utah Data Center," under construction in rural Utah
 for the National Security Agency. The facility is designed to help 
protect cyberspace, NSA official have said. But 
Wired Magazine published a cover story earlier this year
 arguing that the facility will be capable of monitoring every email and
 text message sent around the world -- including messages to and from 
U.S. citizens. It is scheduled to come online in 2013.
The NSA 
denies that the facility will be used to spy on Americans, but it's 
hardly far-fetched to surmise it will have such capabilities.
Explosion of such technological capabilities is why clarifying digital Fourth Amendment rights is so critical, Crump said.
"No
 data is more personal than email correspondence," she said. "Email is 
deeply personal and private. It is an unfiltered view of our thoughts 
and a catalog of our relationships stretching back for years. Government
 agents should not be allowed to troll through all of our most private 
correspondence without proving to a judge that they have probable cause 
to believe that a search will turn up evidence of a crime."
