There are many problems with American police today but the ones that do a good job should still be respected.
i agree  A police officer, also known as an officer, policeperson, policeman, policewoman, cop, police agent they have lots of names for the same role
That's cool, where does the word "cop" come from?
well In most countries, "police officer" is a generic term.
That makes sense. What types of duties do the police perform?
well i have heard that United States, "police officer" or "officer" is also the rank held by a regular police officer 
Interesting, do you know how many police officers there are in America?
im not sure but we ahave aton, olice officers may be sworn to an oath, and have the power to arrest people and detain them for a limited time
