How would a doctor (Mark Sloan) have known when the Federal Reserve was going to burn $100,000,000?
Detective Sloan is shown firing an automatic weapon while attacking the hideout. He is holding the rifle such that the buttstock is completely below his left armpit and is shooting by spraying the area wildly while holding the weapon sideways. There are a number of errors here. Sloan is right-handed, as is evidenced by him later being shown with his pistol holster on his right side and holding the rifle in his right hand. Also, no one trained in the use of firearms, such as a police officer, would ever hold nor operate a rifle in this manner.
FBI Agent Wagner is shown with a cross draw holster on his right hip for his service pistol. The FBI doesn't allow hip level cross draw holsters, only cross draw shoulder holsters are allowed.
