Research Paper

I am still not really sure where i want to go with my paper.  I want to discuss how technology has an impact on small arms because I think that a lot of time is spent talking about nuclear weapons and not about small arms.  Some ideas for topics that I have are letting ex military and police teachers carry concealed weapons to school.  Or make it legal for someone to buy a pistol in the state of north carolina at 18 since they can by a rifle at 18.  I don't understand why an 18 year old can buy a weapon that is capable of doing damage at over 500 yards when they can't have a pistol that is not very effective outside of 50.  I also think if teachers have served in the armed forces or are and ex cop they should be able to carry a concealed weapon to school if they take a course in order to defend themselves and their students in case of a school shooting.  These are just a couple ideas that I have about small arms in our every day lives.  I would like some advice as to where to go with these ideas or if any of you have any other ideas that would be interesting.
