Let me see if I can add a few points:
1) Remember that true assualt weapons are fully automatic. When they talk about banning assuault weapons, they REALLY mean semiautomatic versions of machine guns, like AK-47 knock offs, M16 clones (AR-15) and such. There are ALREADY laws against owning automatic weapons. When Obama said, "an AK-47 doesn't belong on the street," did he mean a full auto, or a sporting (semi-auto) rifle? So "assault weapon ban" is not a correct term as it relates to the public, as they are ALREADY banned (without the proper permit.) The media, or the mis-informed, see an AK-47 in a crime, and figure it must be full auto, when it probably isn't.
point- if this is about banning assault rifles, they are already banned!
2) Taking guns away wont stop crime. The first murder happend with the first people (biblically speaking) when Cane killed Able. He used a rock, not an assault rifle!
I truely believe that some liberals (Rosie Odonell) believe that if all guns vanished today, the sun would come out, the children would play, and all the people of the world would hold hands and love each other for evermore in peace. Guns have been around for about 500 years. People have been murdering each other since the begining of time; a lack of a gun did not stop Alexander from conquering Asia (how many tens of thousands of people do you suppose he killed on his march?) , or Cesar from invading Europe.
Point- if this is about people commiting murder only because a gun was available, check your history about ancient Rome. Lots of murder / robberys, no guns!
3) Check the writing of our founding fathers, and see what the had to say about the right to bear arms.

"Laws that forbid the carrying of arms...disarm only those who are neither
inclined nor determined to commit crimes. Such laws only make things worse for the assaulted and
better for the assassins..." Thomas Jefferson
Point- Do you really believe that current legislators are wiser than our founding fathers??????
4) If anti-gun activists pass one ban, it opens the door for further bans. A ban of private weapons all together opens the door for future tyranny. I am not saying Obama is cable of tyranny; but his successors could be. Dont think it could happen in the U.S.? I wonder if the Chinese thought it could happen to them (MAO Zedung) how about the jews (Hitler), or the Cubans ( Castro) or the Russians (Stalin and Lenin) or the Shia's, Sunnis, and Kurds (Sadam Hussein) or the Cambodians (Pol Pot) or the Ugandans (Edi Amin). The list goes on.

Point- In 1929, the Soviet Union established gun control. From 1929 to 1953, about 20 million dissidents, unable to defend themselves, were rounded up and exterminated.
5) May anti's believe guns are scary, and evil, and we have no business possessig them. Check your statistics. If we ban things that kill, then cars are first!
Anti- "well thats silly! We don't need guns, but we need cars!"
Pro- "No we don't. Take a bus! Walk! Ride your bike! Cars are convenient, not necessary!"
6) Americans use firearms to defend themselves from criminals at least 764,000 times a year.

Point- You will hear about it on the news if a Murder, or robbery takes place. You won't hear about it on the news of an individual thwarts a robbery by brandishing a weapon. Happens every day. A gun is a deterrent.
Sorry for the rant. I hope some of this is helpful. Good luck on your report!
