It is hardly a reach to imagine some mean person pulling a hitch pin. I've seen YouTubes of this happening between truck drivers - one gets hacked-off by another and the other guy finds his pin release pulled the next morning in a truck stop while doing his pre-drive check.
Heck, I've had a guy seriously brake-check my on highway; never could figure out why - probably having a bad day and didn't like that I passed him (and I only drive 65). There are more-and-more rude, vindictive people around than ever before.
I always lock my hitch pins with a keyed lock. But I still check things after every time I'm away from the lash up.
It's good to hear in this case that at least no one got hurt.
