Factual error: When Janet dials 911 from her cell phone, we hear a low tone followed by two higher tones. In reality, 911 is a high tone followed by two lower tones. Additionally, she dials 911 and puts the phone up to her ear without ever pressing the "Talk" button. (01:35:10)
Bill Cox: You designed the software, you find me a way in.
Jack Stanfield: I wouldn't know where to start.
