Half of archaeologists who witness looting don't report it

A peer-reviewed survey found that nearly half of field archaeologists who encounter active archaeological site looting do not report it to external law enforcement or archaeological authorities. This is not because they do not care — the vast majority reported multiple encounters with looters — but because reporting mechanisms are ineffective: local police lack training to investigate antiquities crimes, federal agencies like the FBI have minimal capacity for ARPA (Archaeological Resources Protection Act) enforcement, and there is no centralized reporting system that connects field observations to actionable law enforcement response. The real pain: looting destroys archaeological context permanently, and even when artifacts are later recovered, their scientific value is drastically diminished without provenance. The global illicit antiquities trade is worth billions of dollars and attracts organized crime, yet the front-line observers — field archaeologists — have effectively given up on the reporting system. The structural cause: ARPA violations are federal crimes but enforcement is handled by agencies (BLM, Forest Service, NPS) whose law enforcement rangers are spread thin across millions of acres, prosecution requires proving the artifacts had archaeological value exceeding $500 (a threshold set in 1979 and never adjusted for inflation), and conviction rates are low enough that reporting feels futile.
