Why is speaking a fluent second language a bonus for State Police Officers?

The reason why knowing a second language is important for State Police Officers is because they work with a lot of different kinds of people who speak different languages. If a police officer doesn't know what the other person is saying because of the language differences, they might not get the help that they need. For an example, if a person saw someone doing a crime and wanted to report the crime and tell them what happened but only spoke their language. How can the police help or catch that guy without knowing the facts? Without knowing what he saw. Police officers are there to help and protect their community. There are tons of reasons why it is a bonus to know a second language for State Police Officers.
