Pro Gun Control Arguments?

So, I have to write an argument paper for my English class. My teacher had us pick subjects to argue on then told us we have to write the opposing argument of our viewpoint. I need some help finding some legitimate arguments to search further into on why people are for stricter gun control laws, then I can go from there... and no need to tell me reasons why gun control doesnt work (I already know the arguments from growing up with a father who's a proud NRA member)
