Similarly, you can read the NJ knife laws a thousand times and still be missing out on the fine details, or altogether lost. The knife laws in this state can be so confusing that there have been reports of cops arresting a civilian by mistake believing he was carrying an illegal weapon. So, understanding the knife laws here can save you unnecessary harassment and costly court engagements.\nConfusion Over The Second Amendment \nThe Second Amendment of the United States Constitution reads: "A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed." Thus, the State cannot infringe upon your right to own, or carry a knife, except in limited circumstances.\n \nThe above statement has caused confusion among many including law enforcers and scholars. Scholars have come to call this theory "the collective rights theory." This theory of the Second Amendment asserts that citizens DO NOT have an individual right to possess guns and that local, state, and federal legislative bodies, therefore, possess the authority to regulate firearms without implicating a constitutional right.\n \nSo what does that boil down to?
