Faking Beheadings - The Home Game

I heard about this a few days ago, which the duped media bought as legitimate at first, and I've got one thing to say about that:

It shows how easily one of those beheadings can be faked, whether it be by some domestic computer expert not affiliated to a political organization, or an equally if not more capable intelligence agency (though that may be giving them too much credit (j/k)) that is affiliated with geopolitical and military interests.

What do you do when people outside the government start heavily manipulating the media and the news cycles?? O_o
