I think this is a great prompt, and I'd like to see it filled.
However... I wouldn't say that most of what happened in JJ is right in Matt's backyard. Alias Investigations is, yes, but most of the bigger scenes in the show take place in places like Central Park, on Broadway, at the Brooklyn Bridge, on the banks of the Hudson River and at the ferry terminal. These are not really in Hell's Kitchen. The show takes place all over NYC. Nearby, yes, but then New York City is a huge city with millions of people. It's not that unlikely that Matt wouldn't really be aware of everything going on.
Just pointing that out, especially because any prompt (and I suspect some fic going forward) may sort of compress the geography and population of the neighborhood significantly without realizing it.
