Factual error: O'Brien ask the uniformed officers to "push back the perimeter" because it's too small. When a crime scene perimeter is established you can always shrink but never enlarge a perimeter because everything outside of it has all ready contaminated by other people, officers, press, etc. (00:18:45)
Factual error: There is no Federal Reserve Bank in Los Angeles.
Factual error: When discussing the set up for the Federal Reserve Bank heist, Merriman states that this federal reserve branch destroys on average $30 million each day in worn $100 bills by shredding. If that were true, this branch alone would destroy about $7.5 billion in $100 bills each year. The Fed Reserve system consists of 25 branches, and according to its data they only replace a bit over $1 billion per year in worn $100 bills. If that was divided between all 25 branches, that would be only $40 million in $100 bills each year at each branch, not the $30 million per day that Merriman quotes. (01:30:00)
Factual error: In the big shoot out scene in the "corridor" highway next to the train tracks (supposed to be the "Alameda Corridor" highway and train-way in LA) they are on a two lane one way road (as the Alameda Corridor is one way) through construction with barriers and temporary orange signage set up. However when you see the sheriff's team advancing on the Merriman and his men retreating in the direction of traffic, there are a large number of yellow permanent traffic signs (turn arrows and speed signs) up on posts and poles facing traffic the wrong way. This is obviously either a two-way road or a one-way road going the other way normally, but because it was next to railroad tracks they thought it could pass for the one-way southbound Alameda Corridor. Also, it is afternoon and the sun is on the driver's side windows which means they must be going northbound, which cannot be the Corridor. Part of the shootout scene shows a passing elevated transit train that is yellow-golden across the bottom half of its cars with green logo boxes at the end of each car side - no LA trains look like this. Lastly, as they are driving up to the shootout location they pass a whole lot of tall trees, some obviously evergreen pines, and sizable green spaces - there aren't any along the Alameda Corridor or that part of LA, and rare evergreens in that town (unless you count cypress or sequoias which these aren't).

Suggested correction: Only Big Nick and the other cops knew Donnie had served. They had his records pulled up. Donnie never told the other crew so he could look inexperienced enough to not run the whole show. It made it easier to double cross both sides later. Donnie played the fool to get the upper hand.
50 cent told Merrimen "he was a marine for a minute" also Donnie has an Eagle, Globe and Anchor tattoo (Marine Corps).
