The Boston massacre has rendered visible the big black hole at the heart of the United States of America.
Who did this and why?
Was it al Qaeda delivering blowback for American drone attacks and Guantanamo torture? Or was it a Timothy McVeigh type homegrown terrorist making a grand gesture about gun control on Tax Day? Or was it a random school shooter type attack by a lone wolf suffering from psychosis?
The fact that no one has taken responsibility only increases our collective uncertainty and anxiety. We've seen this before. When will it end? Is a call for retribution President Obama's only response?
There is a crisis in America. A crisis of ethics and a crisis of imagination and, above all, a crisis of leadership.
When will an American leader step forward with a vision that can end the senseless, escalating violence? A violence that is spiraling into the undoing of our once great nation.
