If you haven't already I recommend reading the book 22 Murders by Paul Palango. He lays out a lot of the, shall we say, inconsistencies in the rcmp version of events, including when the first 911 calls came in, when they knew it was Wortman and when they knew he was in a cop car and in uniform. He also touches on Wortmans connections not only to cross border smuggling (mainly cigarettes and guns from the states), organized crime, and local law enforcement but two of his victims were prison guards that he had a long association with, and during his rampage he was at their house for hours before burning it to the ground. And yea, tie that all into the lack of a proper inquiry and investigation and the maple gladio lable doesn't seem too far off the mark
