Why was last year DC’s most violent in decades?
As a rule, people don’t like to commit crimes when others are watching. That’s why most violent crime occurs at night, and why erecting street lights in high-crime areas causes murders, carjackings and robberies to plummet. Essentially, if you want to stop crime, you have to let wannabe criminals know you can see them. By that standard, Washington, DC should be crimeless. The eyes of the world are constantly trained on our nation’s capital. And thanks to the residents of a certain public housing project on Pennsylvania Avenue, Secret Service motorcades and Marine helicopters seem perpetually on patrol. You would think that, for all these reasons, it would be hard to commit crime inside the Beltway.
