Questions & Answers about keisatsu wa kanojo no mujitsu o kakuninshita.

What are the readings of the words in this sentence?

They are:

• 警察 → けいさつ
• は → pronounced わ here, because it is the topic particle
• 彼女 → かのじょ
• の → の
• 無実 → むじつ
• を → pronounced お
• 確認した → かくにんした

So the full sentence is read:

けいさつ は かのじょ の むじつ を かくにんした。

Why is は used after 警察?

は marks 警察 as the topic of the sentence.

So 警察は means something like:

• As for the police, ...
• The police ...

In this sentence, the police are what the sentence is mainly about, and then the sentence tells you what they did.

A learner might wonder why this is not 警察が. That is also possible in some contexts, but it changes the nuance:

• 警察は彼女の無実を確認した。
  → talking about the police as the topic
• 警察が彼女の無実を確認した。
  → puts more focus on the police as the ones who did it

So は is natural if you are simply stating what happened regarding the police.
