Here in Canada they seem to think they get a “halo effect” from the rights the USA created and 53% of us defend.
But the degeneration of the most important Amendments (IX, X) certainly makes it clear why the IV and V are all but meaningless.
And in a country where the concept of Free Speech (no Amendment I here) is anathema, we should not be surprised that the rest of the BOR is confusing to them.
We have the same rights to bear arms in Canada as you do in the US. Unfortunately, many don’t know this and government passes illegal laws.
