THE HAGUE, Netherlands – The Dutch government passed a new terrorism bill Friday, granting law-enforcement authorities far-reaching powers of investigation and allowing them to hold suspects for up to two weeks without charges. Intelligence agents will be able to use currently banned techniques such as infiltrating terror cells for undercover operations and telephone taps, a Justice Ministry statement said. They will also be allowed to use entrapment tactics, such as bogus sales transactions. The law must be approved by parliament. “There also will be more possibilities to gather information, detain suspects and conduct preventive public searches,” it said. “The events in Amsterdam and The Hague have made clear that wider powers to prevent terrorism are desirable.” The ministry was referring to the Nov. 2 killing of Dutch filmmaker Theo van Gogh, whose throat was slit allegedly by a young Muslim radical who associated with a suspected terrorist cell. In The Hague a few days after the murder, terrorist suspects wounded several policemen during a botched arrest attempt. Two young men holed up in a residential neighborhood for a day before surrendering. The new law also lowers the level of proof needed to hold a suspect believed to be plotting terrorist activity, said Justice Ministry spokesman Wibbe Alkema. The problem in the past, Alkema said, has been insufficient grounds to detain someone who could be preparing an attack. If the law is passed, authorities will have more time – up to two weeks – to build a case and bring charges. “In the initial stage of custody, there will no longer need to be serious suspicion, but only a reasonable doubt,” he said. “That could be someone who is believed to be involved with a network that has been under observation for some time.” One such case is that of Samir Azzouz, an 18-year-old Dutch Muslim on trial for allegedly plotting bombings of prominent Dutch landmarks. Prosecutors will be able to approve the use of spot searches of people and cars in public places that could be potential targets, such as an airport or a sports stadium, if there is suspicion of an attack plot.
