Tomorrow, between the hours of 8 a.m. and 6 p.m., a mock crime scene will be set up on the south side of Union Square Park. While there are tons of fake crime scenes set up around town every year for the sake of entertainment, we've received a few alerts regarding this one, so it may be BIG. All we know right now is that it will include an emergency response, and the NYPD will also be on site. Now, let's try to figure out what TV show this is.

Currently, the most action-packed shows filming in New York are Gotham (mostly filmed at Steiner Studios), Law & Order: SVU (possible, but that seems like a long shoot for L&O), this new Christian Slater hacker show, Blue Bloods, Elementary (filming at Silvercup Studios today, but often out on location), The Mysteries Of Laura (maybe they've confused Union and Times Squares?), The Following and The Blacklist. Our money is on one of the latter two (they tend to go big with their crime scenes)... but we're secretly hoping this is for some dark episode of Broad City, also filming now.

UPDATE: It is The Blacklist.
