This might help: https://www.in.gov/ilea/about-the-academy/basic-training-tier-i/ I recon that the "thought" process in many professions is to limit the amount of people licensed to practice. It covers a big spectrum from plumbers, to lawyers, to accountants and MD's.What I am comparing is the “thought” process into the training. It takes a plumber x amount of years to get full pay scale and you have to go through years of schooling. At the end you make a lot and you’re given the permission to perform your job. Police officers according to the post above are trained for a week and then given a gun and sent out? That’s what I was comparing.
