Other mistake: Throughout the episode, all the interactions with the characters went from day to night except for Commissioner Reagan chaperoning his grandson's class at the museum. It stayed daylight the whole time at the museum. (00:27:14)

Question: Why why does Danny always yell, "hey!" When he's is a half a block from the perpetrators which gives the perpetrators 1/2 block head start running from Danny. Why doesn't he wait until he's close to him and he wouldn't have to chase him so far?
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.
