No Way Out - S3-E3
Other mistake: Higgins is asked if she can hack a security feed from an office. She replies that she can do it, but it will only be audio, no video. When she hacks it, is only video, no audio. (00:14:10 - 00:15:35)
The Day Danger Walked In - S3-E5
Factual error: Higgins, Thomas, TC and Rick are locked in a freezer. Their barber friend is tapping his horn in "a pattern" Higgins says is Morse code, and announces that he tapped "move back." Not really. I know Morse Code. All I got (along with a few undecipherable things) was TOERT NMU ETM CEA OFJ DER WK. No way that spells "Move Back."
The Day Danger Walked In - S3-E5
Other mistake: In the middle of the storm, telephone service goes out. Yet later, one of the robbers sees an emergency alert on his phone and says it is getting worse. If cell service is out, there is no way he could have received that.
