For most of the thirteen-hour crime spree, Wortman was driving a replica RCMP cruiser and wearing an RCMP uniform. On December 4, 2020, three people, including Wortman's partner, were charged with supplying him with ammunition later used in the attacks.[5]
Police were criticized for not using Alert Ready to warn the public about the attacks, as well as not responding to reports of Wortman's behaviour and previous acts of violence. An investigation into law enforcement's response to the rampage, including the decision not to use Alert Ready, was launched.[6][7][8][9] A public inquiry into the law enforcement response was declared on July 28, 2020, following escalating criticism of the investigation's lack of transparency.[10]
The attacks are the deadliest shooting rampage in Canadian history, exceeding the 1989 École Polytechnique massacre in Montreal, where 14 women were killed.[11] On May 1, in the wake of the attacks, Prime MinisterJustin Trudeau, following through on a 2019 campaign promise,[12] announced an immediate ban on some 1,500 makes and models of "military-gradeassault-style" weapons,[13] including two of the five guns used in the attacks.[14] The ban included the Ruger Mini-14, which Wortman obtained illegally within Canada, while the other four guns he used included a stolen pistol from an RCMP officer who he killed and three guns obtained illegally from the US.[15][16]
