Terms and Exigency: Definitions and Key Ideas that need clarification, correction, and deepening “Predictive Policing: The Role of Crime Forecasting in Law Enforcement Operations” says that poor-quality data is made from data censoring, systematic bias, and relevance. The book says that systematic bias results from how the data is collected. I would like to add that systematic bias also results from how the algorithms themselves compute their results. Algorithms are not unbiased processing calculations. In addition, systematic bias also contains police officers bias. Greater tendency to imprison one sort of group or in one certain location highlights those areas to the algorithms. A term that must be defined is crime displacement.…show more content…
Evaluation of hotspots effects need to account for all these different displacements. A term I speak of in relation to crime displacement is diffusion of benefit. According to Guerette, “The opposite of crime displacement is diffusion of crime control benefits. Crime diffusion entails the reduction of crime (or other improvements) in areas or ways that are related to the targeted crime prevention efforts, but not targeted by the response itself.” I speak more on diffusion o f benefit in the next section. It also appears in Table 1 on the right column. Regarding exigency this text tries to fulfill several different things. I am correcting a gap regarding crime displacement. PredPol, a software company that provides algorithms and computation to police departments, claims that crime displacement does not occur. I’ve found evidence and examples by reliable sources that prove the contrary. Crime displacement does occur. In addition, I am correcting a certain perspective. There are some that believe predictive policing results in less biased policing. This is actually not true. Predictive policing incorporates all the previous biases of the system into the new one. Predictive policing also adds its own biases to the system. Algorithms aren’t unbiased, although many, specifically some police chiefs, believe they are. Those who adopt predictive policing believe it will decrease or diminish biased policing or racial
