When Nolan saves the lady from electric shock after the car accident, the burn from the power cable on the lower left front of her shirt disappears when/after Nolan drags her clear of the car.
The bottle of drugs has no lid on it in one shot and continues to when Nolan has it in his hand, after looking at the woman in the bed, the lid is back on the bottle.
When Nolan picks up the empty prescription bottle, the top line of the label reads "Percocet", a combination of oxycodone and acetaminophen (paracetamol). The strength however, is given as 50mg-- Percocet is a combination drug, and therefore would have two strengths (which range from 2.5mg to 10mg for the oxycodone and stay at 325mg for the acetaminophen). Lower on the label reads "each tablet contains... 50mg of sertraline", also known as Zoloft, which does come in a 50mg strength.
An attorney found in contempt of court in LA, just like Wesley is, would not be brought to a police station but straight to LA County Jail. Also, contempt of court is already a felony, so the judge would not send the attorney to a police cell as if it were school detention. Once declared, the attorney goes to the jail and is processed.
While handcuffing the suspect in the stairwell, officer Lopez puts the handcuffs on his right wrist and she says "stop resisting, it's over." Immediately after this the shot transitions to her handcuffing the left wrist and you can quickly see the cuffs on the right wrist are not fastened. This is confirmed by watching the scene in slow motion. This reveals the actor was not actually handcuffed, which is uncomfortable.
