End the sale of malicious video games such as "Call of Duty, & Black Ops"

I have witnessed, as many other Americans and people around the world, senseless slayings that have taken place to innocent people. While this may not be the answer, I believe that there certainly are some negative influences placed in the mind of those that participate in these horrific games. These games teach killings, and murders. While many might say that, "it's just a game" or "it's harmless" try telling those advertisers that pay millions of dollars to put a 30 second thought in your head during the Super Bowl. Those advertisers realize that if they can just get the thought in your head, they have increased their chances of you acting upon that thought. I feel that these games desensitize people to killing, so when the thought arises in their head to take someone's life, they have already prepared this in their mind by doing so on these video games. The games are not just played, but they are inter-active, causing the person(s) playing to take part in the violence. Lastly, but certainly not least, it was noted that the gunman in Connecticut was dressed like one of the gunmen on "Call of Duty, Black Ops." Please, help me help our world by signing the petition to stop the sale of these games.
