A lot of people are missing the point re "banning flights". It's kind of like the gun control debate. Guns don't kill, people do. In this case airline flights don't kill, it's the infected people that get off the flight.
The solution is simple. Refuse entry to any person who has travelled to Sierra Leone, Guinea, or Liberia in the last 21 days. At least its a start.
Passports exist for a reason.
The solution is even simpler, revoke the 13,500 visa to the Ebola countries and don’t issue any more. Then it doesn’t matter what circuitous route they take, they won’t be allowed in this country.
