I wouldn't trust the body guards if I were her, to keep her where-abouts secret. Money talks. Just two body guards would cost her $10,000 a week, it was reported earlier. But who knows what the going rate is.
Well considering my buddies working for Blackwater in Iraq were making $500-1500 a day it could easily be 10 large a week for multiple guards working round the clock. These aren’t just mall cops, she needs ex operators or the like. She will get what she needs - the anticipation of a big publishing payday will ensure the money is there for her security needs. And I wouldn’t be concerned about them selling off her location - that would be incredibly unprofessional and do you really think some nut wants to go after her that bad that he is willing to pay 20k+ to find out where she is? I doubt it. People will forget all about Casey in due time. Once the story fades from the media no one will care anymore.
