The first time we see the police whiteboard it has "W Delta Z" and "W Delta Z = Cov" written on it (even though no corpse has borne the "v" at that point). But in the next shot the board says only "W Delta Z = Co".
When Daniel Leone gives the slip to his police escort he does so in a Jeep with a hard top, a few minutes later, still driving the same jeep, the engine stalls but the jeep now has a soft top on.
After Gelb is arrested, the whiteboard shows the full, unmarked Price equation. In the next shot, the equation is marked up in red.
When Detective Jackson is looking through Daniel Leone's criminal history, one of the entries states that he was charged with possession of "crystal methadone." There is no such substance. It would either be crystal methamphetamine or simply methadone - most likely the former.
At about 49 minutes in, in a scene at the police station, a sticker on a file cabinet reads "COUNTRY; 98.8 KSRS". FM stations in the US only advance in odd 10ths (such as 98.1, 98.3, etc). Also, KSRS is a radio station in Roseburg, Oregon...not exactly New York City.
