Stop the presses! Research indicates there are more muggings after dark! The abstract from the November 2013 issue of the Journal of Research in Crime and Delinquency (50(4)) is here and copied after the break.
A Stab in the Dark?I'm being a bit facetious. There is nothing wrong with doing research that confirms and quantifies the obvious. Every once in a while a researcher hits the research lottery and finds out that what "everybody knows" is not true after all.

Objectives: Test the influence of darkness in the street robbery crime event alongside temperature.
Methods: Negative binomial regression models tested darkness and temperature as predictors of street robbery. Units of analysis were four 6-hr time intervals in two U.K. study areas that have different levels of darkness and variations of temperature throughout the year.
Results: Darkness is a key factor related to robbery events in both study areas. Traversing from full daylight to full darkness increased the predicted volume of robbery by a multiple of 2.6 in London and 1.2 in Glasgow. Temperature was significant only in the London study area. Interaction terms did not enhance the predictive power of the models.
Conclusion: Darkness is an important driving factor in seasonal variation of street robbery. A further implication of the research is that time of the day patterns are crucial to understanding seasonal trends in crime data.
