Swearing in ceremony?

My readers know about my having high fun at the expense of hyphen (or the lack of one). The latest is a news report with the title: "Swearing in ceremony today".

With a hyphen ("swearing-in"), I would have assumed that the corporators would be taking oath of office that day.

Without a hyphen, as it was published, I take it that the corporators plan to hurl profanities at each other during the ceremony. How noble, how true to life!
