Nichols holds a German newspaper in his hands about the killing of a banker. In the headline it says "... Beider Meinhoff" which should be "Baader-Meinhoff". Near the end he shows the same newspaper again and they corrected it.
When Shelley is in the bank she cocks her Tech-9 twice without ever firing it. The first time is when Nichols first enters the bank, she raises her gun and the sound effect of it cocking is heard, though it seems very unlikely that given the situation she didn't already have a round chambered. Then when Nichols starts moving in her direction the gun is once again heard being cocked, but this makes no sense as she never even fired it (even if she had fired it the gun had a 40 round magazine), all cocking it again would do is eject a live round from the chamber and load another one in from the magazine.
