Why is "Alberta Provincial Police" trending?

Wikipedia Overview

The Alberta Provincial Police (APP) was the provincial police service for the province of Alberta, Canada, from 1917 to 1932. The APP was formed as a result of the Royal North-West Mounted Police (RNWMP) leaving the prairie provinces during the First World War due to a lack of sufficient resources in light of its increased responsibilities for national security and reluctance to again enforce Prohibition law recently put into effect by the Alberta government after its experience doing so during territorial times. The RNWMP was replaced by the newly created Alberta Provincial Police on March 1, 1917, which remained responsible for provincial policing until 1932, when it was eliminated as a cost-cutting measure during the Great Depression. The APP was known for its tumultuous beginning, battles against rum-runners and bootleggers during prohibition in Canada and the United States, as well as its remarkable efficiency and professionalism which endeared the force to Albertans.
