How to convince my parents to let me play shooting games?

I am thinking about buying an XBOX 360, and getting the new call of duty game. I can easily afford the 360, and the only thing stopping me from buying one is that my parents haven't, to this point, allowed me to play shooting games. It's SO annoying!
Does anyone have any ideas that I can mention to my parents to convince them??

(by the way, I've decided 360 beats ps3. however, im still willing to listen to some arguments in favor of the ps3)

Thank you!!
