Citizen Media legal guide
The Berkman Center’s Citizen Media Law Project has a site that’s rich with information, written in non-legalese, about your rights and liabilities as a blogger (and general citizen media person) in the U.S. There’s lots to browse there, and it’s all quite concise and helpful.
For example, the section on whether it’s legal to record a phone call you’re having with someone else says, in part:
Federal law permits recording telephone calls and in-person conversations with the consent of at least one of the parties. See 18 U.S.C. 2511(2)(d). This is called a “one-party consent” law. Under a one-party consent law, you can record a phone call or conversation so long as you are a party to the conversation. Furthermore, if you are not a party to the conversation, a “one-party consent” law will allow you to record the conversation or phone call so long as your source consents and has full knowledge that the communication will be recorded.
In addition to federal law, thirty-eight states and the District of Columbia have adopted “one-party consent” laws…
This is an excellent resource.
