I saw this on the Escapist website:

I notice this part at the end:
I wouldn't call it the Call of Duty effect as much as the Halo effect. He came in to a Pawn Shop I was shopping around at and asked for an "Ess Em Gee" (Submachine gun). The owner said that he didn't carry them. He then asked if he had any sniper rifles. The owner showed him a .270 (I believe). As the punk (hat cocked off to the side and his pants at a level where a belt would not allow them to fall) looked down the scope, he asked how to "zoom it" (a common feature of scoped rifles in video games). The owner showed him how to magnify and clarify the image. The punk said that he was just used to the rifle doing that for him. Finally the owner asked what the kid was looking for to which he replied "I just want to headshot some noobs! Like in Halo!" The conversation quickly degraded from that moment and ended very shortly.
Pretty much a game like Call of Duty drives people to google obscure words and visit websites they normally wouldn't visit. What I find scary here is that someone, inspired by Halo, Call of Duty, or whatever, suddenly decides they want to get a REAL gun, so they can shoot noobs in the head in real life? Are we going to have to have a license to screen people to see if they are illsuited to play videogames?
