yes its stupid but, and i would never suggest doing this especially for a $60 video game, someone that is pointing a gun at you within arms reach even with his finger on the trigger can not discharge that weapon in the time it would take you to grab the barrel and step out of the way.
Wow, you've been watching too many Jackie Chan movies there kiddo'. Unless you are a top notch martial artist, Special Forces ( or similar ) or maybe a boxxer, thinking like that will get you killed. I bet I could stand in front of you with an airsoft pressed to your head and if you tried that you'd have a nice welt on your forehead and some BS excuse of how the sun was in your eyes or how no one said "Go".
This kid was an idiot, lets say the gunman had no intention of shooting him over the game in the first place. The gun was indeed real and during the struggle the gunman might have accidently ended the kids life.
If you ask me, the best case scenario would have been for the kid to get shot in the struggle, lose the game anyways and for the gunman to get away. Now idiots that think they can take on an armed assailant are going to be more likely to try and they will die.
Life is not a video game you idiots, you get one life and any self deffence instructor will tell you DO NOT TRY TO DISARM AN ARMED ASSAILANT IF THEY WANT YOUR MONEY! Give them your money, your watch and your stupid ass game that you can replace because " He/She loved His/Her games more than life itself" does not look god on a tombstone.
