I would first have to be convinced there is a problem. Adopting tech from the US or elsewhere that requires some form of dedicated security, a la F-35s is an issue that needs to be addressed, but limited to where the tech will be. Is there a CF base that currently has the gate down on a regular basis?
It's one thing to say that certain weapons or authorities are needed on domestic soil, but it's another to make it legal. If you give somebody a gun and a role, it is assumed they have the ability to exercise it under the appropriate circumstances. I'm not sure the military's concept of unlimited liability applies on domestic soil.
Where is this "exploitable seam" that cannot be addressed by current resources properly funded? CSIS, CSE, Immigration, federal law enforcement?
