The Society of Professional Journalists Code of Ethics
The Society of Professional Journalists first issued this code in 1973 to provide guidelines for responsible reporting. It is followed by journalists with integrity. www.spj.org/ethicscode.asp
From the spj.org website:
The SPJ Code of Ethics is a statement of abiding principles supported by explanations and position papers that address changing journalistic practices. It is not a set of rules, rather a guide that encourages all who engage in journalism to take responsibility for the information they provide, regardless of medium. The code should be read as a whole; individual principles should not be taken out of context. It is not, nor can it be under the First Amendment, legally enforceable.
