The relationship that Raymond Fisman and Edward Miguel found between the extent of corruption in a country and the number of parking violations committed by the country's United Nations delegates in New York isn't perfect.

Does this observation invalidate Fisman and Miguel's conclusions about whether the parking violations data provide evidence in favor of there being a culture of corruption in some countries? Briefly explain.
