An increase in bank robberies in Connecticut's Gold Coast caused law enforcement to question why bank robberies had increased there while they decreased in Manhattan.
"...law enforcement officials tend to agree that relaxed bank security - often driven by an attempt to create a friendly atmosphere, without barriers between tellers and customers - can attract robbers..
If the barriers matter, this may explain the migration of robberies to the suburbs. "The most common areas to have these barriers are the urban areas, the cities," Agent Siegel said. "Once they get hardened, the robbers tend to go out to the suburban counties."
