This is what I and other Freepers have been saying from the start of this Ebola episode. Why do terrorists have to sweat about sneaking weapons onto planes, at great cost and difficulty, when they can take advantage of a disease? A simple vial or capsule containing diseased fluid, consumed just prior to going through a security checkpoint at an airport, each taken by a dozen or two co-conspirators willing to be martyrs to the cause, can bring this country to it's knees. And there is very little that can be done to prevent it.
Yep. Once here and showing symptoms, mix some body fluids into a pink misting fan: walk down a crowded NYC street, stand over a crowded DC subway stairwell, upper decks at a baseball game, etc. Go to an amusement/water park for the day, an outdoor concert, clubbing at night, swim in a resevoir, maybe even get yourself arrested and thrown into GP for a day. The possibilities are endless.
