A couple of months ago as we were walking East on Greene Avenue between Waverly and Washington we noticed in our peripheral vision someone approaching fast from behind. When we spun around, it was a teenage boy, probably about 15 years old, who had crept up and was hovering inches from the back of our head mocking us provocatively to the clear delight of his jeering friends. Ever risk-averse, we quickly walked out into the middle of the street and starting dialing on our cell phone. With a few shouts, the pack continued down the block. We jogged back to a police car we had noticed parked back on Vanderbilt, told the cops what had happened and went home. The next day we heard that a woman had been mugged half an hour later a few blocks from there by a bunch of teenagers. We’ve heard of several similar instances in the area in recent weeks. And it’s not just Clinton Hill. A post on Brooklynian describes how a trio of teenage girls (19, 17 and 12) mugged five different people in Prospect Heights on Saturday night (and how only one of them decided to press charges) and an email we received yesterday told of a violent mugging of a twenty-something male by a group of boys at around 8:15 Monday night at Dekalb and South Oxford Street in Fort Greene (above). What can the community do to combat this activity? Obviously greater police presence would help, but given the paltry resources the NYPD devotes to this part of town, it’s going to take a lot of vigilance on the part of residents in terms of reporting even small incidents of harassment and pressing charges. And everyone should be aware that a lot of these muggings are happening during daylight hours, often between the end of school and dinner time, so it’s a good idea to minimize iPod and cell phone usage during those times. Please use this comment thread to document other similar incidents that you know about in recent months as well as to suggest ways to address the problem.
