Using the IRAC analysis approach very briefly answer this: Does Bob have claim of the tort of False Imprisonment against the car salesman.?
Here is "I:" Does False Imprisonment exist.
Here is "R" (the elements of false imprisonment): False Imprisonment is (1) intentional (2) confinement of a person (3) without legal privilege (4) for an appreciable length of time.
You need only complete the IRAC analysis by doing the A and C sections of the analysis.
A: You do the analysis, evaluating whether each element exists.
C: You state your conclusion based on your analysis..
