When meeting with some members of parliament I have used a gun control analogy to explain digital locks applied to communications technology. A minor form of gun control is being hotly debated in parliament and the media in the context of a private members Bill C-391, which has "repeal of long-gun registry" in its title. A highly controversial form of third-party control over communications technology is part of copyright Bill C-32, even though this key aspect of the bill is not yet adequately understood.
I felt it might be an interesting thought experiment to compare and contrast these two proposals and the political debate surrounding them. In my case this thinking was useful for me to better understand the opponents of the Canadian firearms registry, and thus it may be helpful in allowing others to better understand opponents to legal protection for technological measures.
