While there is little argument that the violence in Mexico caused by the country’s drug war has reached epidemic levels, data over how much of that spillover has reached the U.S. varies greatly.

Though there are discrepancies in numbers – data differs from study to study – the violence seems to be contained in Mexico, though there are concerns that it could endanger American citizens, according to a Government Accountability Office (GAO) report.

“Law enforcement agencies have few efforts to track spillover crime,” the GAO report stated. “Law enforcement agencies have varying concerns regarding the extent to which violent crime from Mexico spills into southwest border communities.”
