Wall Street Journal columnist James Taranto has a thought about Samantha Yowler, Jansen Young and Amanda Lindgren, three young women whose boyfriends were killed while protecting them in Aurora. Here's his thought: "hope you were worth it!"

Taranto, who brags on his Twitter profile that Greg Gutfield once called him "sharp," later described his Tweet as "challenging." It is, I guess, a bit challenging for a Journal opinion writer to understand that selfless personal sacrifice doesn't occur within a rigorous cost-benefit analysis. Certainly, Taranto seems a bit challenged.
