When Harper (the rape victim) is asked to describe the attacker, she says, "Tall"; when asked "How tall?" she says, "Tall-ish." But later, at the station, Benson shares the description and says the attacker was 5'8" -- which isn't tall by American standards (avg height for a man in the US is 5'9.5"), nor would a woman of Harper's height (5'6") consider a 5'8" man "tall."
When Harper Anderson opens the door inward to her boyfriend's building, a camera, camera man, and boom mic are very clearly visible in the reflection on the door glass.
