A police academy teaches recruits that the world is divided into sheep, wolves, and sheepdogs, that they are warriors protecting the innocent from predators, that hyper-vigilance and readiness for violence are professional necessities - and graduates emerge with mindsets that shape how they perceive every encounter. Another academy teaches recruits that they are guardians serving communities, that de-escalation and communication are core skills, that most situations can be resolved without force - and graduates emerge with different mindsets that shape different encounters.
