In the months after the storm, the presence of the National Guard was, for me, one of the most potent symbols of the oddness of our situation, the militarization of a major American city: sand colored Humvees rolling down the streets full of Guardsmen and women in full combat gear, toting large rifles. Then, gradually, they faded away, and one day they were gone. We were "normal" again.
Now they're back. After a recent spike in violent crime, they have been invited to return to the city to patrol flooded neighborhoods, freeing the police to focus on high-crime areas. Weird, weird, weird.
