They don’t use compatible radio systems. They DID assist by taking other unrelated calls on behalf of the RCMP to free up members, but they weren’t able to safely integrate on the primary call. Truro police on the road couldn’t talk to RCMP and vice versa. You can probably imagine how hugely dangerous that is. I’ve worked on the road in a jurisdiction where multiple uniformed police services overlap and don’t share radios. It can be a huge problem. Those other police services were better used taking other calls, and they did.
Bear in mind that for a considerable portion of the night he was *not* an active shooter (or ‘active threat’ in our parlance). His behaviour had changed, he had gone to ground, though all police knew is there were no longer new scenes coming in. That changes some aspects of the response. With an active threat you throw everything you have at the threat based on information about their location, which will generally continue to flow in. Once they are no longer actively killing, you slow it down, work the problem, gather info, and try to find, contain, and safely capture the suspect. In this case once he stopped killing for the night and took off, what they had was an immensely overwhelmed gaggle of night shift members, a critical incident command team establishing itself, an already horrendously complex investigation, and a whole lot of info to try to gather, corroborate, and act on. They were flooding resources in from the length of NS and from NB, but that takes time, and police services don’t ‘ad hoc’ an ORBAT on the fly nearly as capably as the military does.
There will undoubtedly be a full inquiry of this, likely resulting in something similar to the MacNeil report following the Moncton murders. Like that one, it will take time.
Transparency is important, but we also don’t know what other investigative angles are being worked, likely including the trafficking of firearms across the border. We will learn more in time, but wanting answers now does not mean we’re entitled to answers now. I’d rather they run absolutely everything down and then offer that up. The public generally has no clue how tremendously complex a major investigation is. Even with a dead suspect, all of this still needs to be meticulous in case it forms the basis for subsequent legal proceedings involving other parties.
