Isnt that just another way of describing the same thing.
People complain about police and police actions all the time, its just like any other business or industry or profession.
When you lowered all the standards not just once, but lowered them, then lowered them even more because you didnt get the desired diversity, then lower them again, what do you get standing wolf, you get a lower quality of police force over years, a less capable police force with less confidence.
Now add to that the most qualified for promotion are passed over for what ever reason and over years that erodes the quality and confidence and overall environment and morale of the entire institution.
