This link is of little value. Why should anyone believe that Big Data could never be used to help prevent terrorist attacks? Rather, lots of things can help us to prevent terrorist attacks. Depending on who you talk to this may include: hire more police officers, accept more refugees from Syria, record and analyze everyone's conversations and movement, stop bombing civilian populations, expel all Muslims, and withdraw US forces and other support from the Middle East. As this article specifically supports Israeli methods to "track down enemies of the Israeli state", I'll add that I support Sweden's position and its recognition of the Palestinian state. In that context, note also the statement "[suppose] a large percentage of people from Country X have performed some form of terrorist attacks in last years." Who do you think that "Country X" is supposed to be? Bear in mind that the US estimates there are no more than 200,000 terrorists in the world. (Says https://www.techdirt.com/articles/20140506/14033627137/how-many-terrorists-are-there-not-as-many-as-you-might-think.shtml https://www.techdirt.com/articles/20140506/14033627137/how-m... .) From the US perspective there are no countries where 'a large percentage of people ... have performed some form of terrorist attacks in last years'.
