A random, childless dude shows up at the daycare (likely on Christmas day, when the place would be empty), acting unhinged and demanding "where are the children," and acts offended when they won't let him in.

That's a totally normal and predictable response on the daycare's part.

EDIT - This whole saga is obvious rage-bait trolling.

If this was actual journalism, the guy would have went during normal business hours, and brought a child with him, with a fake story like "I'm looking for a daycare for lil' Billy here, would you mind showing us around and telling us about the place?"
