Ahead in the distance we could see the main gate, but there was a sea of cars, none moving, people standing, milling around, waiting nervously, perhaps fearfully, as heavily armed MPs and military working dogs searched every square inch of every vehicle, searched every bag on every person, all the while keeping a vigilant eye on the long alley we were stuck in, and on the hundreds of rooftops that overlooked that alley, wary but aware that there were people out there who would gladly hurt us again if given the chance.
