From ZDnet, the New York Times and TechDirt comes this story: New York City has subpoenaed a TXTmob server that was used to coordinate street protests during the 2004 Republican national Convention.

The city’s lawyers are litigating civil suits brought by hundreds of protesters who were arrested during the convention. All the city’s lawyers want are the records of every user and message sent on the system.

TXTmob can be used to resend text messages to hundreds of mobile phones in real time. The software is available on the Institute for Applied Autonomy’s web site. Wikipedia has a good article about the service.

Tad Hirsch, the creator of the TXTmob software, does not want to release the information on his server:

“There’s a principle at stake here,” he said recently by telephone. “I think I have a moral responsibility to the people who use my service to protect their privacy.”

Hirsch has appealed for donations on his web site. Hirsch says some of that data no longer exists. He’s been busy writing his dissertation at MIT.

Who’s got the data?

There are many web and mobile services like Facebook and Twitter that could be used to coordinate protests, according to this Wired article. Groups need to consider who operates their messaging servers and who controls the data for their web services. Hosting an application like TXTmob on one’s own server is one way to avoid a Web portal or service provider’s restrictions.

Even so, the server has to be connected to the Internet, and the text messages are resent to subscribers through the mobile phone carriers servers. The telecom carriers routinely archive text messages sent through their systems, as I mentioned on 3 February 2008, and the carriers will provide messages and logs if subpoenaed.

I may have to revisit the article I wrote last year for the Encyclopedia of Business Ethics & Society. Jim Dempsey of the Center for Democracy and Technology had the following response regarding the TXTmob subpoena in Wired’s article, and I agree with him:

“In civil cases, the law seems to prohibit the disclosure of stored communications in response to a civil discovery subpoena because the Electronic Communications Privacy Act of 1986 prohibits disclosure of stored messages of any kind,” he argues. “The subpoena clearly is not enforceable.”

But he adds that the case is a reminder that federal privacy law is in dire need of an update to reflect the new era of massive stored communications and web services.

“The notion that any litigant can get any information about any person is an 18th century rule that now can now encompass terabytes of information, and I think it also has an impact on service providers who don’t want to become one-stop shops for every litigant in the country,” he says.

A local example

On Monday, Two hundred protesters used email and phone calls to organize their event at Fort Street Mall in support of Aloha Airlines. The US Bankruptcy Court is in 1132 Bishop, above the MSIS classrooms in the Frear Center. My office is a few steps away. This Honolulu Advertiser article has details and a few pictures.

I didn’t see anything about the march at DontFlyGo. Their web site is difficult to navigate, and the domain name is missing an apostrophe on the banner. Based on this Honolulu Advertiser article, there’s little indication that local groups might try to use mobile messaging to boycott go! flights.
