I agree with Eye95. Never equate lack of knowledge with lack of intelligence.
The Vast majority of LEO's are anything but stupid. You try to follow the syllabus of any police academy. Generally 20- 39 weeks of 40 hours in the classroom plus the after hours homework. A test every week plus one every 4 weeks on EVERYTHING covered to date. It gets harder as you go. The average day is 18+ hours for at least 6 days a week.
More and more are requiring either an AS or a BS degree for consideration to be accepted to the academy with a bust out rate of about 25-40% of those who start.
The average intelligence of the recruits is probably in the 115-130 IQ range, where average in the general population is considered to be 100 IQ.
Nearly all if not all would qualify for OCS or any other officer program if the were in the military and applied for it. Most would be encouraged by their officers and NCO'S to apply.
I speak from experience.
