It looks like all four copycat terrorists might have gotten away although one man wearing a backpack was seen being taken into custody. In at least two of the incidents, an asian man was seen running. In one incident, a man's rucksack exploded and the man cursed. I wonder why no one jumped the bastards? Anyway, looks like their bomb maker screwed up something.

Update: One was chased by people but not sure what happened afterward.
