TITLE: The Berlin Massacre and the Killer Between the Cracks
SENTENCE 1: So on Wednesday night, after a SWAT team stormed two apartments in Berlin, and came up with nothing, at least one officer was forced to conclude Amri has gone “over the hills.”  Such are the latest lapses in a history of bureaucracy and bungled police work that goes back more than five years—the kind of story that has led to growing fears about security in the European Union, and growing calls for more controls and less tolerance even in the United States.
SENTENCE 2: We now know from the “wanted” notices posted on all the world’s media that the man most likely to have murdered the truck’s driver then raced the tractor-trailer through that festive holiday scene, killing 12 people and injuring about 50 more, is a 24-year-old Tunisian petty criminal and alleged “soldier” of the so-called Islamic State known by the alias Anis Amri.
SENTENCE 3: We saw it with the Kouachi brothers who slaughtered the staff of Charlie Hebdo in January 2015, and with many members of the Brussels-based cell that carried out the savage attacks in Paris in November last year and in Belgium in March.
