The use of K-9 s in police departments

This is an analytical and descriptive essay, but you need to think more about the analysis side. Talk about the background of K-9’s and when they were first used in police stations. Talk about how the utilization of trained police canine teams (K-9’s) for building situations or to search for a suspect can represent a considerable benefit for police agencies. Find scholarly literature such as court cases or examples in which the literature studies police practices before K-9 use and after K-9 use to support that K-9’s are a considerable benefit for police agencies. So for example, what were police practices before K-9 use and after, and how was police behavior changed by the use of K-9’s. (For the sources only use scholarly articles)
