Milestones - S9-E12
Other mistake: First we see Jamie in a Ford CVPI with license plates 7554 like a couple of times before in the show, a minute after he's seen exiting a 2015 Ford Taurus with plates 82399. He answers a 10-85 while supposedly driving in the CVPI but somehow he manages to change in less than a minute to a Taurus. We see the exterior of the car, but the car's interior corresponding to the Taurus is seen a few seconds earlier. (00:03:35 - 00:04:20)
Answer: It's a common cop show plot device. If the police on the show always acted in the most logical way (i.e. not alerting a suspect to their presence) the show wouldn't have the opportunity for an exciting foot chase.
