Sometimes it works out. I live in the bad part of town. (The whole damned town is bad if you ask me, but this is the "bad" part.) I walk to work. It's a few blocks. Currently I'm working the graveyard shift, so it's not the best time of day to be wandering around. Now, I work in a federal facility and cannot bring a firearm with me, as there's no place to lock it up outside of the facility and I'm unwilling to stick it in a bush or something, so I'm left with a knife. But the knife laws are fairly restrictive here...except for knives carried by craftsmen for work. As it so happens, I'm a craftsman and I'm on my way to work. Now I can carry something that's large enough to actually do some harm should the need arise, but won't get me into trouble with my employers - who have a significantly more relaxed view toward such things, interestingly enough. Those archaic laws can be annoying, but make sure to read them all. Sometimes they've already given you an out.
