Corruption comes in many different forms. There's the old style graft, and then there's the corruption of the very soul of an agency by politicians seeking to change the nature of the job. Graft occurs everywhere, to a greater or lesser extent. If kept to a minimum, it's hardly noticed, and doesn't interfere with governments core duties. In other places (Chicago comes to mind) it is the reason for being for government. My own town is historically somewhere in the middle there, most of the time. The new type of corruption, which seeks to transform the profession of LE into something else, is different. Different because it masks itself as 'reform', and spreads like a virus...carried by the Good Idea Fairy. Particular incidents are used and overblown to show a 'systemic problem' in an agency...and they have the fix. Usually PERF is brought in (which not only wants to transform the profession, they want to change society), or similar reforms are proposed. A new emphasis on 'traffic safety' usually occurs during this time as well. Demographic tracking of enforcement activity is instituted, and cops begin getting the message. The overall atmosphere also leads to an often undiscussed loss of trust....the cops begin to lose trust in the judgement of the public, as well as vice-versa. Recruiting is tailored to demographic needs and creating the "new face" of an agency....and this cycle then feeds on itself. The focus begins to shift to enforcing infractions against other wise law abiding citizens....and avoiding the scary bad people, who even if you're one of the cops inclined to pursue them, you quickly realize it is unwise from a career standpoint. So you adapt, or leave. Training is increasingly geared towards non-confrontational 'skills', Implicit Bias, inclusivity, etc. But occasionally....a cop is unable to avoid being in a situation where they bad guy shoots at them...and they react, sometimes ineffectively, sometimes badly.....and the cycle begins anew.
