Preventive measures?: Electronic trackers can monitor the movements of vehicles in real time. Pictured is the Christmas market at Breitscheid square in Berlin, Germany, Dec 22, following an attack by a truck which ploughed through a crowd at the market.
LONDON: The attack on a Berlin Christmas market showed the devastation that can be wrought by the simple act of driving a truck into crowds, and the problems in preventing another massacre.
The attack in Germany on Monday, in which 11 people were killed by the truck in addition to the murder of the Polish driver, mirrored a militant raid in the French city of Nice in July that killed 86.
