Pretty much what the above poster with the 4 laws said...
... as well as mandating that every town or city with a population of over 1,000 have a city militia made up entirely of armed members of the city (not military or police, just civilians like you and me) who have access to weapons similar to those that the US Infantry use, and train to deal with disasters like floods, fires, hurricanes, tornados, major civil unrest, terrorist attacks, etc, as well as patrol or monitor the streets (much like a neighborhood watch) and calling the police when crimes are witnessed. Again, these people would not be state or federal forces, they would be comprised of, and led entirely by civilians.
Sometimes I wonder what would have happened in New Orleans had there been more armed citizens working together for the greater good. Isn't that a major part of what the second amendment is? People actually forming and maintaining militias to serve the community? And I'm not talking about certain extremist fringe groups claiming to be militias, I'm talking about a genuine, citizen run, public oriented group of people.
Also, I would like to see the legalization of open and concealed carry everywhere in the US and it's territories. If you can legally own a weapon, I don't see why you can't carry it however and where ever you see fit.
I'd also really like to see firearms education be mandatory in school. For example, make it a requirement to graduate high school that the student pass a weapon's safety course and qualify with a pistol and rifle at a school range... similar to the course that most CCW holders go through. Common sense rules and basic weapon's familiarization seem like a good thing to teach everyone.
I would also like to be able to buy a machine gun, at wal-mart, with no papers, but that's probably asking too much... But I definitely want to see all GCA and NFA laws repealed.
Just my two cents.
