If I was required to shoot someone in defense on my (percieved) freedom I don't think I would balk at the task.
Of course there are better ways to deal with things and we as a country spend a lot of time and money trying to teach others how to play nice in the sandbox. It doesn't always work though.
Although I wouldn't want an oversized invasion force like the US I still, as a taxpayer, would prefer to have a moderate size and more importantly WELL TRAINED defense force in place.
Perhaps they should have the police clean the snow or parks and task the army with stopping looters. There would be a lot less future looters that's for sure.
