To arrest our President, Barack Obama by officials for committing treason for attacking the 2nd amendment.

Obama has been supportive in his campaign and in legislative act to limit the 2nd amendment. This is treason.
The oath that our law enforcement and military take says exactly this "I, [name], do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic." Which means the politically correct and justifiable thing to do would be to arrest the President of the United States of America, Barack Obama for treason.
Even if they pass laws that would "make" it the "law" that doesn't mean that our oath takers need to enforce or let those laws slide by. That is unless, our government's word is more important then our "contract".
