Newark isn't the only place outside NYC the NYPD have been carefully watching. They got to New Haven and Philadelphia, too, although they seem to have spent their time monitoring student groups (and even going whitewater rafting) rather than staking out tasty food. What good is that, I ask you?
Then again, the NYPD's been doing this sort of thing for nearly a century.
Maybe I just have to wait until they stake out more restaurants in more places. They certainly did check out a lot of places inside the city.
