The 13th Crime Congress on Crime Prevention and Criminal Justice in Doha next week will set the tone over the next five years for the way the world confronts crime.

Back in October 2013, rescuers came across a grisly scene in the Sahara desert close to the border between Niger and Algeria. Spread out across a 19 km radius were the bodies of 92 people; most of them women and children. All of them had died of thirst as they sought to escape the punishing sun. The migrant group had been traveling in two trucks, but the first one broke down and the second left for repairs.

The migrants were stranded. After waiting five days, the group struck out to look for water. Only 21 people survived when they managed to reach towns on the Algerian side of the border.
