I think police officers should have a 4y college degree plus one year in training and be paid more money. Less cops, better cops.
I think police officers should be paid low wages with extremely minimal advancement. They should be encouraged to enter the work force after a few years. The same with the military (I got out after the Soviet collapse because I practice what I am preaching) and firefighting.
Basically, I disagree with your assertion that there should be a law enforcement class and a military class or any other government and a sheep class. You phrased it in more palatable words, yet at its heart that was what you advocated.
My belief is that all able bodied citizens should serve a period working either military, law enforcement, or fire fighting when they are young - then form a reserve pool that can be recalled to those tasks when needed.
You want an exclusive class set apart for those things then you can pay their pensions. Also when they become no longer held accountable and we have to identify how that came to be well...the problem is the people who were too stupid to understand the checks and balances the framers inserted into government. This was one of them.
Take your elite government class desires (which you want us to pay for) and shove them.
Completely disagree with 4yr college degree. Colleges are nothing more than liberal indoctrination centers any more.
