i disagree entirely. Whether one is dangerous or not depends not on his capabilities, but solely one his intentions. By your reasoning, anyone trained in any sort of self-defense is dangerous, and thus should be treated as such by the police. One can carry all the weaponry in the world and be trained extensively in its use, but circumstances alone dictate whether or not the person is dangerous. I sa US Marine, home on leave, playing with his infant child considered "dangerous"? i would say no, most people wouldn't consider him dangferous in such a situation. Would that same Marine, on patrol and in under fire in some Middle east warzone be dangerous? I'd sure hope so.
As for the case of the CCW holder shooting a cop over a traffic stop (if that were indeed the case...without citation, its simply hearsay)....One's man's actions should NOT adversly affect the freedoms others enjoy. The idea of... "If it only saves one life, its worth it" is a seriously flawed idea that only idealists cling to, IMO. While tragic, isolated incidents like that shouldn't be used to stereotype all concealed carriers. There are bad apples in every bunch, but that doesn't mean every apple crop should be destroyed in order to prevent a bad apples from reaching store shelves
