ELI5: Why would you ever report a homeless person?

In what way is the MDY you write about any different from the YDM in the screenshot? The important thing, that they’re in random order, is the same for both, right?

And as for spoken language, it’s not like any normal person would say “September fifteenth” now, is it?

Is that not the format that’s actually used in the US? I mean, it’s utterly insane, but a lot of people really are used to having the components of the date in random order.
