JUST as winter follows autumn, political exploitation inevitably follows tragedies. It happened after the Oklahoma City bombing, the Moore tornadoes, the Newtown school shootings — you name it and politicians and/or special interest groups will exploit a tragedy for political gain. It’s occurring now with two high-profile exonerations of white police officers who took the lives of black criminals this summer. What happened in Missouri and New York has not only unleashed protests. It’s also spawned maneuvering among politicians and policymakers to not let a tragedy go to waste.
