Although people dislike crime, they love to discuss it. Up until now, the public has had to rely on RNN, or MNN (which feed the Gothamist Crime Map), or Spotcrime.
Each service has its own quirks.
Now, NYC gov is in the act, and has launched its own website and promises provide reliable crime and incident info after the fact.
Without further a due: http://maps.nyc.gov/crime/
Note, this site is unlikely to replace the other sites, because it won't provide news as it breaks. So RNN won't get competition.
The change on Nostrand will make the one on Franklin look minor
