Interesting article from the NY Times regarding criminal behavior modification and police helicopter utilization in Los Angeles. From the article:
"Crime shapes cities — even Paris, the “City of Light,” takes its nickname, according to one story, from streetlights first instituted as part of a 17th-century police operation — but the reverse is also true. Cities get the types of crime their design calls for. This logic extends even down to their bedrock: Tunnel jobs are almost unimaginable in granite-based Manhattan, for example, but the soft sedimentary rocks of Los Angeles — a former seabed — make it more susceptible to subterranean crime. Infrastructure also plays a major role in permitting or preventing entire classes of criminal activity. The construction of the city’s freeway system in the 1960s helped to instigate a later spike in bank-crime activity by offering easy getaways from financial institutions constructed at the confluence of on-ramps and offramps. This is a convenient location for busy commuters — but also for prospective bandits, who can pull off the freeway, rob a bank and get back on the freeway practically before the police have been alerted. The maneuver became so common in the 1990s that the Los Angeles police have a name for it: a “stop-and-rob.”"
