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.
