I'm going to mention 2 things about the Nigeria Police Force that I guarantee most people here don't know, which will provide context for why these things keep happening and why no single police officer including the IG himself has the power to change anything.
One thing I will say is that Nigeria's current economic woes are 100% artificial and caused by deliberate policy choices.
Nigeria is so large and so resilient an economy that if its government simply *stays out of the way* and does nothing, the country will sort itself out.
