Although this piece is focused on smuggling heritage items in Algeria, I have included it because this sort of trafficing is a problem shared by all nations with heritage worth trading, and this seems like a particularly interesting approach:
"Algeria is stepping up efforts to curb the theft of its archaeological treasures. The police plans to recruit archaeology graduates and curb the illegal trade of stolen items. . . . Four regional police units have been set up in Oran, Constantine, Ouargla and Tamanrasset to track down people involved in this illegal trade. The units make inventories of archaeological sites and carry out aerial surveillance. In the future, the police plan to step up these efforts by recruiting students from institutes of archaeology."
