My little brother wants to be a police officer when he gets older.

That is great! A police officer is also known as an officer, police person, policeman, policewomen, cop, police agent or police employee.

Wow so many different names. Is it hard to become one?
1_Wizard
No it is not too difficult to become, one but it does require a lot of training. Some police may be trained in special duties such as counter-terrorism, surveillance, child protection, VIP protection, civil law enforcement and investigation techniques into major crimes including fraud, murder, and drug trafficking

It seems like a dangerous profession to be in.

Yes it can be but they have sworn an oath to protect and serve the citizen in the country. We are lucky to have good law enforcement available to us to keep us safe and the community in order. :)
