Here's an interesting post:
We have taken the philosophy of customer service (a square peg), and repeatedly tried to force it into the law enforcement profession (a round hole). This was a well intended idea that someone took from the world of business and tried to make it work for their law enforcement agency, and it has continued to spread. The problem: we don’t have customers as police officers. We swear an oath before God to uphold the Constitution and the laws of the United States. That is our solemn contract with society, not a customer service policy similar to the one at your local gas station.
