No. We've tried that. Education never hurts anybody, but it does nothing but limit the applicants we have to choose from in LE. If anything, the age required to be a LE should be higher. Immaturity is biggest factor in most of our problems. There is nothing that can be learned in a classroom that determines whether a person will be good cop, or not. Nothing.
I believe there in your statement is the main problem in the LEO community, Most of the complaints are about officers in their 2 year of service, they are just getting confident in their position and yet do not have the experience a senior officer does. And then situations get out of hand. A older start date would allow for more training and more time to develope skill sets needed in life and as an officer.
