Mugging in the Rain, Just Mugging in the Rain...

A question, occasioned by New Haven's recent crime wave and more recent bout of wet weather: do you think that mugging rates increase or decrease during inclement weather? On the one hand, rain would seem to create conditions favorable to muggings: non-muggers are more thin on the ground (fewer "eyes on the street") and those who are out are likely to be harried and distracted. On the other hand, one imagines that muggers are probably less motivated than the general population, and are more likely to be deterred from going out by bad weather.

What do we think? Is rain the ally of the urban highwayman?
