There exists a decent real world example of "a tale of two police strategies" in two demographically similar cities: Juarez and El Paso. Juarez and El Paso are situated across from each other along the U.S.-Mexico border. In some ways they are the same city, with many residents traveling across the border each day. Juarez is the second most deadly city in the world, at over 100 murders per 100K population [1]. El Paso has just 3.3 murders per 100K population [2]. The difference is that the police and legal system work better in the U.S. compared to Mexico. In many parts of Mexico, gangs run the streets, and officials are either in bed with gangs or often intimidated by gangs [3]. That's what fills the power vacuum in the absence of effective policing.
