What do you call it when police interrogate a cow's husband answer key?

The answer to this pun is Question-a-bull

Bull is an english term that is used to define a more aggressive species of cow, which is correlated as more masculine or manly.

By combining the words question, a, and bull, we create a word that sounded similar to 'questionable' which is really appropriate to use when we see a police weirdly talking to a cow.
