A little over a year ago I left ISAF Joint Command headquarters at the Kabul International Airport. One of my jobs as an intelligence analyst was to research and gather information on insider attackers and help get as many of those individuals who had escaped after conducting those attacks on the JPEL/kill list. This post explains a bit why I took the job seriously, and a bit personally.
Despite all the insider attacks, or as we called them, green on blue attacks, I never felt unsafe or threatened on the base. There were plenty of people around (not that that would have mattered) and very few Afghan soldiers. I was more concerned with the pack of jackals that wandered around the base than I was of being shot by in infiltrator. Not even the insider attack had occurred on the base a couple years prior to my arrival gave me much concern.
Yesterday, an Afghan in a security force uniform (some say police, some say army) killed 3 US contractors and another Afghan.
Just a unpleasant reminder that you're never truly safe over there.
