An interesting theoretical scenario was recently posted here on FR that went something like this:
1. An Email to or from Hillary included the schedule and plans for Ambassador Christopher Stevens’ visit to Benghazi for the time-frame of the attack.
2. Hackers of the Hillary Server had access to that information.
3. Interested parties in Libya gained access to that information and planned and executed the attack that ended with the death of Ambassador Stevens.
That could be what happened. We don’t know but Hillary does.
You left out one part. Stevens begged for increased security, and Hillary (herself) denied it, leaving him vulnerable. Didn’t I read that the Marine guards they did have had no bullets in their guns?
