When I drive across any of the Potomac River bridges, the law deems that this once "law-abiding" citizen is now the worst sort of criminal - illegally carrying a concealed handgun. What happened to me at the mid-point of that bridge span?
Here's another problem that is partly illustrated by your question. Is it the mid-point of the bridge span where you become a criminal, or is it at one end or the other? When you as a citizen can't determine exactly when you are acting within the law or not, what meaning does the word "criminal" have? Have you ever looked at the CFR? Good grief! How many miles of shelf space does it take up, not to mention state and local government regulations?
When the law becomes so complicated that you can't be sure whether or not you're in violation, is paranoia far behind? More than anything, I think that's why people fear interaction with abusive LEO's, the sneaking suspicion that they're a "criminal" but they just don't know it yet. Ayn Rand was exactly right...
I've seen so many threads started by relative newcomers and some not-so-new posters along the lines of "I did (FITB) in this situation, was it legal?" Otherwise intelligent people speak up with the only good answer, "check the laws in your jurisdiction and get a lawyer." Why? If it takes years of legal training and study to know what to do in a situation that is over literally within seconds, then we've gone too far with the "law".

There are even Latin terms in the law for what you describe, mala in se, crimes which are recognized as morally wrong (rape, murder, theft), and mala prohibita, crimes which are crimes simply because a law was passed prohibiting them (speeding, possession of certain substances the government doesn't like, possession of certain items the government doesn't like). The former everyone agrees on, the latter, as you say, are more "elastic".
In teaching CCW classes, I've seen so many folks completely ignorant of the laws regarding use of force in defense of oneself that I'm amazed there isn't a class on it in High School like there is for Driver Training. Then again, if they did that, people might realize what their rights actually were and how the government is infringing on them. Couldn't have that, ya know. :banghead:
