Confidence in their ability to get away with it. They've been pardoned once, why not again?
You're right to ask the question, it's an unsettling thought that something like that is actually plausible.
Both, sorta.
Art is a form of communication. It is up to the author/artist to ensure the message they want to convey is both clear and understood to their target audience.
However, no matter how hard you try there will always be some who don't interpret it as intended. These typically fall outside of the target audience, but their interpretation is still valid.
If the target audience still misinterprets, their interpretation is valid, but the artist did a poor job communicating their intention. This does not necessarily mean the art is bad though.
Canadian here. It sounds like a nice idea, but honestly the vast majority of Canadians do not understand how the EU works at all, or what benefits/donwnsides there are to joining.
This also ignores whether the EU wants us to join at all. I also do not see our government doing this any time soon, maybe if things continue like this for another 10 years or if the US drops out of NATO.
It's fairly short-sighted of you to think the FBI is the only target these people have in mind.
