The eldest son is called criminal police, the second is called bailiff, and the third is called armed police. What's the father's last name?

The eldest son is called criminal police, the second son is called bailiff, and the third son is called armed police, taking his father's surname. This is a question similar to a brain teaser, which uses people's daily habitual way of thinking and only understands the meaning of the question literally. And ignore the most direct meaning expressed by some words themselves. In the four sentences of this question, a word with the same meaning is "call". Many people intuitively know what the name is. Actually, it's their surname, so his father's surname is "called".
