Whose Help Is on the Way?
研究发现，逮捕结果关键取决于接警的警官，高逮捕倾向的警官更可能是白人且经验较少，他们更常使用武力并做出更多低级别逮捕。
Police discretion has large potential consequences for public trust and safety; however, little is known about the extent of this discretion. I show that arrests critically depend on which officer responds to a 911 call; 1 standard deviation increase in officer arrest propensity raises arrest likelihood by 40%. High arrest officers are more likely to be white and have less experience. I find mixed evidence that arrest propensity is related to arrest quality. High arrest officers use force more often and make more low-level arrests, while they also have a higher share of low-level arrests that result in conviction.
