This is something that MANY teachers have been trying to point out as being a result of not holding students accountable for their efforts and work in school. We are ignored, and we are tired of being ignored. It's like standing beside a house on fire on the lower right corner, telling the fire department exactly where the fire is located, and then having to stand by and watch them chop down the front door of a house that is 4 houses away. At some point, you just get tired of trying to save people when folks won't listen to you. So, you decide to let them handle the dumpster fires without you because there are better things to do in life than giving yourself a concussion by beating your head against a concrete wall.
Results = Teacher shortage
That mindset will result in a police shortage as well, and it looks like it's already happening. Good cops, like good teachers, have other options than a career of being thrown in the ocean with their hands and feet tied. At some point we'll only have cops and teachers who are too dumb to do anything else for a living.
