Now that is an interesting question.
Consider the following:
In NMSA 30-7-2.4 it makes it a crime to carry firearms on/into "the buildings and grounds of a university, including playing fields and parking areas of a university, in or on which university or university-related activities are conducted." Obviously this includes student housing and the general campus.
The NM State Constitution says the following, in Art II, Sec 6:
No law shall abridge the right of the citizen to keep and bear arms for security and defense, for lawful hunting and recreational use and for other lawful purposes, but nothing herein shall be held to permit the carrying of concealed weapons. No municipality or county shall regulate, in any way, an incident of the right to keep and bear arms.
Now, because of NMSA 30-7-2.4 prohibiting the students from carrying weapons in student housing the law is obviously prohibiting both keeping and bearing of arms (by citizens)... but the statute even prohibits students from carrying arms to defend themselves, all of which are prohibited from being laws by Art II, Sec 6 of the NM Constitution.
So, if I were to open carry on campus, or even keep a weapon in student housing, would I be breaking the law?
Whoever knowingly or willfully [...] teaches the duty [...] or propriety of overthrowing or destroying the government of the United States or the government of any State, Territory, District or Possession thereof, or the government of any political subdivision therein, by force or violence, or by the assassination of any officer of any such government; [...] Shall be fined under this title or imprisoned not more than twenty years, or both, and shall be ineligible for employment by the United States or any department or agency thereof, for the five years next following his conviction.
The Declaration of Independence quite clearly states:
[...] when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.Now, if you take a look at the link, it is the House's own copy of the US Code from which this is being pulled; so, the Declaration of Independence is law.
Now, is the teacher guilty or not of this felony? I will remind you that "ignorance of the law is no excuse."
