Some may not care, but a similar thing happened in Canada. The shooter Gabriel Wortman was likely an informant for the RCMP, because he has been reported numerous times smuggling drugs and guns from the States into Canada, and nothing was ever done about it. He also picked up over $400,000 from Brinks before the shooting. While he was on the lam, the RCMP shot up a community hall because they thought he was in there.

The public has not been given a formal inquiry, just told to "hand over your guns, or else".

EDIT: More details: Wortman's vehicle(s) had numerous hidden storage areas and had a few different rooms hidden by false walls: several at his now-burnt-down cottage and one at his denturist clinic, suggesting he was a smuggler of some kind. Several people who knew him said he was a child abuser, a sexual predator, and a drug smuggler.
