Did you know that if you don't have a Facebook you're more likely to be a mass murderer?
"'not having a Facebook account could be the first sign that you are a mass murderer.'"
'If you’re of a certain age and you meet someone who you are about to go to bed with, and that person doesn’t have a Facebook page, you may be getting a false name. It could be some kind of red flag,'"
"Psychologists have noted that Holmes, along with several noted mass murderers, have lacked any real friends."
(Because all your FB friends are your "real" friends, so when my roommate friended everyone he talked to even for just long enough to learn their name, they are his "real" friends)
So, like Casey Anthony, prosecutors will use your FB against you, and now, like James Holmes, they'll use it against you if you don't have one.
