I just noticed on the Washington Post newspaper web page a nice collection of ways to confidentially communicate between journalists and tipsters. One of them is SecureDrop, which was already discussed earlier. It’s probably a good idea to just become familiar with these channels of communication, even practice it before you need it. Think of it as becoming familiar with your word processor or spreadsheet before you have to write your termpaper with footnotes and tables, or tabulate the results from your survey. Be a scout, and be prepared.
It is interesting to see that US Postal Service (snailmail) is still considered a safe and secure way to communicate.
Do you have information the public should know? Here are some ways you can securely send information and documents to Post journalists.
