Compiled here is a quick primer on many of the most significant pieces of the surveillance revelations and debate. It should answer most questions on the specifics or at the very least give one a jumping off point in their own research. I will attempt to add onto and modify this as the changes come, so check back for future updates when/if new information rolls around. For now, you can check out ProPublica’s FAQ on the NSA’s Surveillance Programs. And also be sure to check out the Electronic Frontier Foundation’s timeline of NSA Domestic Spying, which reveals how persistent and common the issues we’re running into now really are.
