Police officers get such a bad rep nowadays. I may even think about becoming one. Let's hear some positive stuff about them!
Are you sure that you are ready to be a police employee that is a warranted law employee of a police force? 
I'm not 100% sure. That's why I need some advice from you, and some input
You would think that a police "officer" would hold some rank but actually it doesn't. All normal police officers use this title.
Interesting indeed. What's some history behind them?
The police officers job is to arrest criminals and prevent crime. They protect and assist the general public and maintain public order.
