Ok I have this debate/speach class and for some reason I just cant focus on the technical part of the class. I enjoy the class as a whole since we talk about intersting stuff and the teacher is cool, but I get ADD anytime he starts talking about the technical mumbo jumbo.

I know the stuff is really easy but I cant seem to get this assignment done. He gave us a topic "Resolved: gun laws are effective" the other half of the class got "ineffective" ofc. Now we have to give an opening statement and three CDW's. Here is waht Ive done so far, and Im kinda embarassed to say Im having a hard time figuring out what to do next.

Resolved: Gun control laws are effective
Opening statement: Gun control laws may not be perfect but none the less they are an effective way to lower the occurrence of gun related crimes

Claim: Many countries have enacted strict gun control laws to curb rising gun related violent crimes.
Data: In 1997 Australia enacted laws that made personal firearms in most cases illegal and seized over half a million guns. As a result firearms related deaths dropped by 47%.
Warrant: When strictly enforced gun control laws are effective in lowering gun related violent crimes.

Part of the problem is that Im not sure Im doing this right, and the other part is that I dont really agree and am honestly having a hard time finding much through google that supports my assigned position. Can anyone help me out, am I doing it right so far? What are a couple good claims to make?

cliff notes: boost has to wake up at 3:30am for class and is too tired to do his own homework.
