A month ! It has already been a month since four students from the University of Idaho (USA), three girls and a boy, were stabbed to death as they slept in Moscow, a quiet town in this western American state. An eternity for the 25,000 inhabitants who have since lived on the edge… The initial amazement has given way to widespread fear and anger begins to reverberate in a population that does not understand that we still know so little about the circumstances of this massacre.
