'It's becoming an endless parade of brutality'
From yesterday's Washington Post (Greg Miller):
Although the attack was deadlier than other recent cases, Rep. Adam B. Schiff (D-Calif.) said it should be seen as a part of an emerging pattern that includes violent attacks in Canada, Australia, London and Belgium.
"There's a broad pattern of a proliferation of these one-off attacks around the world," Schiff said. "It's becoming an endless parade of brutality."
