The US Department of Justice have released a document detailing how agents can best use social networking sites for their work.
Facebook, Twitter, MySpace and sites such as LinkedIN are all mentioned in the document which advises that Facebook are usually very co-operative in releasing information requested by the DoJ but other sites such as MySpace require a warrant for a request of messages that are less than 181 days old, whilst Twitter doesn’t preserve data unless there is due legal process.
It seems Facebook’s default stance is at odds to other social networking sites.
Slightly disturbing is the notion of acquiring data on witnesses, for data mining, very useful for a prosecuting party.
Not only that, there is also advice on how to use friends lists and whether using fake profiles it legal, the best advice seems to be that it is best not to befriend a DoJ Judge or the defense counsel.
If you are a criminal and want to advertise your misdeeds on Facebook or other social networking sites – it could be said you deserve what you get. There have been a few cases of criminals being caught and brought to justice because of their social networking addiction.
