Defence against whom? We can (and sometimes do) leave our house unlocked around here. You guys must live in a really screwed up place that you have to "carry" for self defence. I can understand why an urban American needs to do things like that but there is nowhere in Canada (at all) where it is necessary to carry firearms to defend herself against other humans. I suppose though, if enough nutbars start "carrying" the rest of us will have to follow to defend ourselves against the freedom-to-carry wankers. That is probably how the Americans got to the sorry state that they are at.
