How to retrieve events for ALL users within date range

@operator

Given a start date and a stop date, I want to retrieve a list of all events in the system in that date range, regardless of user.

I'm using this code. No mention of organizer, resource, etc. anywhere, so I would assume it would do what I want. But it doesn't. All of the events are "public." How can I get all "public" events?

Thanks.
