I just posted this +CNET
article, thanks to some handy FOIA'ing from the ACLU. Here's an excerpt:
*Federal police are increasingly gaining real-time access to Americans' social-network accounts -- such as Facebook, Google+, and Twitter -- without obtaining search warrants, newly released documents show.
The numbers are dramatic: live interception requests made by the U.S. Department of Justice to social-networking sites and e-mail providers jumped 80 percent from 2010 to 2011.*
Unfortunately, we don't even know the extent to which the DOJ/FBI/DEA/Marshals/etc. are gaining access to social network accounts. IP addresses, sure, and port numbers too. But how about +1s or likes? Circle of friends? Pokes? Etc.
Alas, DOJ is -- not surprisingly -- not exactly eager to respond to my questions...
