It turns out that when you leave your house doors unlocked or open, people will take the opportunity to steal your shit. Who knew?
Out of 146 burglaries in Boerum Hill, Brooklyn Heights and Downtown Brooklyn last year, 50 instances occurred due to the residents leaving their doors open or unlocked. Their belief that people are inherently good vanished, along with their belongings. Nice job.
Some of the not-really-break-ins were made more difficult because the victims waited too long to tell the police. They were probably too embarrassed to report it.
