No, i know what you were trying to say. I think the NOLA Katrina thing where they were going house to house diarming people/neighborhoods at gunpoint was more on the nose. But yeah, I do get your point.
Oh and it definitely can happen in Canada. Yup.
What else comes to mind more recently was the searching of homes at gun point by the authorities in Watertown, MA when they looked for the Boston Bomber...
Not sure if there was a “blanket” search warrant in place - never heard if there was - but the pictures of people being hustled out of their homes at gun point was chilling....
