A cultural event poster keeps appearing behind Doug Judy in close-up shots and disappearing in wide shots.
The New Jersey State Police cars do not have the proper insignia/logo on the doors. The actual NJSP logo is a triangle with the single point pointed down. The cars used in this show have the triangle pointed upwards, but with the letters typed correctly so the NJSP name can still be read. Likely done for trademark reasons.
Doug Judy says he went to a Super Target in South Orange, New Jersey. There are no Target stores in South Orange. The closest Target is about four miles away in another town. Also, it is a regular-sized Target, not a Super Target.
Santiago is wearing 2 citation bars that are not issued by the NYPD. Also, NYPD regulations require that the American Flag bar be worn as the highest citation bar - something Santiago would have known.
Captain Holt wears his Commendation breast bar above his World Trade Center Breast Bar. When the WTC bar is worn, it is worn above all other medals, but below the American Flag bar.
Doug Judy claims to have escaped to Amsterdam but the public payphone he is on is not used in the Netherlands mainland, and not even in the Dutch territories in the Carribean, assuming he is lying about Amsterdam as the signs are indeed Dutch.
When Peralta thinks back up is on the way, Doug reveals that he replaced the information in Jake's contacts to route him to Judy. Despite this, when Rosa calls Jake shortly after, she shows up as a contact when it should've come up as an unknown number since he information has been deleted from the phone.
Based on Jake's description, Doug Judy believes that Drake has laid down a beat for them. Drake is a rapper and singer, not a producer or DJ.
