More on the story from GreaterGreaterWashington.org:
The incident puts a tragic veneer on an already-frustrating event, where citizens have to show ID and submit to searches just to enter their own homes. Security agencies are doing all of this in the name of protecting the world leaders, but it's less clear whether it's all necessary. What is clear is that one Washingtonian is dead as a result.
Geoff Hatchard Tweeted, "All this security to ensure that no one gets hurt or dies at the summit, and the security manages to kill someone? Mission NOT accomplished."
