But what happens when the LEOs are getting their data from the NSA? http://www.washingtonpost.com/blogs/the-switch/wp/2013/08/05/the-nsa-is-giving-your-phone-records-to-the-dea-and-the-dea-is-covering-it-up/ http://www.washingtonpost.com/blogs/the-switch/wp/2013/08/05... TOR is not perfect. The NSA, or any other sufficiently large global passive adversary, can defeat it, with global timing correlation. However, a connection over TOR probably requires more resources to track down than a direct connection. On the downside, a connection over TOR may go through a foreign country, which removes any domestic safeguards the NSA does have in place, subjecting it to indiscriminate spying. TOR is also insufficient on its own. You need to use strong crypto, and be careful of your privacy in other ways (cookies, caches, etc) on top of it.
