In short? That it was a huge mess. But that's not enough. An inquiry is trying to get to the bottom of the police response to the worst mass shooting in Canadian history, and around every corner seems to lurk a new detail about delays, misinformation, too many commanding officers and, above all, inaction.

As Canadians learned in horror how police in Uvalde, Texas stood by while a shooter was murdering children in a school, they didn't have to look hard for a Canadian example of how utterly a response to a gunman can be botched. So what are the details? What do we still have to learn? And will there be any change, consequences or closure?
