Giffords枪击案的教训:  负起责任，我们别无选择

枪击案受害者 Giffords' brother-in-law, Scott, the commanding officer, spoke over the radio. Flight controllers in Houston fell silent.

"As I look out the window, I see a very beautiful planet that seems very inviting and peaceful," he said. "Unfortunately, it is not."



"These days, we are constantly reminded of the unspeakable acts of violence and damage we can inflict upon one another, not just with our actions, but also with our irresponsible words," he said.

"We're better than this," he said. "We must do better."
