Jack Reacher: Never Go Back (2016)

Factual error: When Reacher is talking to Major Turner's lawyer Col Moorcraft he is wearing Military Police Corps insignias (Crossed Pistols) on his uniform, not the insignia of the Judge Advocates General (JAG) Corps (Half Wreath with arrow and sword) which is what an Army lawyer would be wearing on his or her uniform.

Samantha: I don't understand. You said you're not a cop.
Jack Reacher: I'm not.
Samantha: What's military police?
Turner: It's different.
Samantha: But... you stole this car.
Turner: It's complicated.

Question: Does Sam really tell the truth when she told Jack that she is not her daughter? Or did she just want to avoid possible danger for both of them?
