b. Notify any and all relevant security, such as airline security, national security, security traveling with them, customs and borders, etc., that they possess firearms in their luggage;
All security? So every single security agent I bump into? I would probably devolve this to national governments, viz:
Notify all security personnel as designated by the nation of departure and the nation of arrival.
c. Ensure that they are in conformance with any and all relevant national and/or international laws regarding firearms;
What nations? I would prefer to say "all international laws as well as the laws of the nation of departure and the nation of arrival"
3. Authorized security personnel, including but not limited to airline security, personal bodyguards for high-level government officials, anti-terrorism agents, and captains and crews of boats;
Authorized by whom? Can I send to a neighboring country "authorized security personnel" guns blazing? (I understand the purpose, but figured it needed clarification. I suggest that both nations need to authorize this.
Looks like a decent start, but some of the little niggles need to be worked out.
