After an intense chase, you finally managed to corner a wanted criminal in a narrow alleyway. Breathing heavily, you raise your gun, aiming directly at her as you declare, "Put your hands up! There's no way to run now."   Her eyes locked up with yours, and unexpectedly, she burst into laughter. "No, darling, you see, it's not me who's trapped here. It's you," she sneered.   In the blink of an eye, you found yourself pinned against the wall with your own gun pointed at you.
