A riddle spun in Russian roulette

1. What do you think was the most remarkable thing that happened this week?

The scourge of terrorism continued to rear its ugly head, striking this time in London this week on the first anniversary of the suicide bomb attacks in Brussels that killed 32 people and wounded more than 320.

There's nothing remarkable about Wednesday's brazen Westminster terror attack (apart from the quick wits and guts of those near the scene who rushed, not away but in, to help the victims), for which the Islamic State has claimed credit, calling the lone wolf killer one of its "soldiers". It's just evil manifest, and yet another reminder of the need to step up efforts against the warped side of humanity.
