The "somebody" who decided that we must stop things from "going boom at all costs" was Stephen Harper who gave the RCMP more work and then reduced its budget! Both CSIS and the RCMP made it clear at the time that they didn't have enough funds but both got budget cuts anyway. Given that the guy in Quebec was supposedly under RCMP observation but was still able to wait in his car for hours before running over the soldier, RCMP surveillance seems to be about as effective as that of the French securityservices. As to Zehaf-Bibeau, the chances of preventing him shooting the guard at the War Memorial were about zero unless you had soldiers with machine guns on all sides! The storming of the Centre Block made the RCMP's policing there look like the Keystone Kops! No amount of security funding would help that. Conspicuously missing in Canada are the kinds of brutal attacks that have happened in the US, UK and France - I believe that has much to do with society here as security.
