At approximately 16 minutes, after Brenda is attacked, her head wound is over her left eye. It continues over her left eye until 28 minutes and 16 seconds when it moves to over her right eye.
Brenda is attacked in her home by an intruder who strikes her, leaving a cut on the right side of her forehead. When the attacker has her pinned, the cut is visible on the right side. In the next scene, she is crying and putting a bandage on the cut-it is now on the left side. However, it is actually her reflection in the mirror what we see after the scene of the attack, which creates the illusion that her wound is on the wrong side. We can even see at times her shoulder and hair, "out" of the mirror, taken from behind. Brenda is looking at herself in the mirror to put the bandage correctly on her wound.
On the way out the door at "The Jones List" headquarters Brenda hits the big red panic button which erases everything from the servers, effectively taking down the whole site, yet a short while later Tao is not only looking at the victim's ad but referencing the meta data to get the time and date the ad was placed. All that information would have been destroyed in the data wipe.
Brenda is at the victim's home, searching for clues before releasing the crime scene, but she isn't wearing gloves on her hands. As a trained police detective she wouldn't be conducting a search without wearing gloves.
