A Crime Deterrent

Bom Dia! There is an island in Brazil near the Amazon Delta that is the home of over 400 thousand Asia Water Buffaloes. Besides the normal use for agricultural purposes and supplying meat and milk, some are now being used by the state police battalion as mounted crime preventers. They are docile and can handle the Equatorial heat as well as make the police more approachable. The link below includes usage by a tannery owner which is eyebrow raising but cannot pass my censor.
