I'm thinking about becoming a police officer! I'm still doing research though!
Good, as you know police officer are generally charged with the apprehension of criminal but also assisting the general public.
It seems like a tough job! Do you have to go to school to be a police officer?
It varies with jurisdiction but of course you need to be trained in a police academy at least.  And they may need to be sworn to an oath.
Oh, okay. I'll check with my local agency. What else should I know before I become a police officer?
Some of these police academies requires various background checks, examination, medical requirements legal training among others.
That's good to know! I wonder what I would see on an average day on the job? 
I believve it would depend if you become a police officer wearing a uniform or a Plain-clothed police.
What do plain-clothed police do? I usually only see the officers in uniform.
Well that is because they are plain-clothed in order to dissimulate as ordinary citizens.
