Third, one must notice the semi-colons appear to respectively seperate the three issues both in the title and in the content of the paragraph. The section claims that a standing army is dangerous to liberty during peace. I interpret this to mean an army of the State such as the National Guard. This portion does nothing to disqualify the first section at all. The section claims that the power of the military should be at the mercy of the Civilians.
Nothing here disqualifies the first section at all.
I consider the title alone a suggestion that this law will violate the Second Amendment's protection against infringment. Disecting ORC 2923.12 is a little complicated. No person shall knowingly carry or have, concealed on his or her person or concealed ready at hand, any deadly weapon or dangerous ordnance. This section does not apply to officers, agents, or employees of this or any other state or the United States, or to law enforcement officers, authorized to carry concealed weapons or dangerous ordnance, and acting within the scope of their duties. This paragraph, to me, grants law officers the right to carry a weapon when ever they choose.
