Shut down the criminal activity's website known as 4chan

This petition is to have the site 4chan shut down as we know yesterday marks a grim day for a small town of roseburg oregon. A guy from 4Chan posted on it "some of you are alright, don't go to school tomorrow if you go to school in the north west" that didn't even go to the collage. Shot up our friends and families. Now I'm not sure about you but on the 4chan site it can be seen. Cyber bullying to deaths to kids that were kidnapped years ago... underage pornogaphy, rape and other forms of illegal sex. After about 10 minutes of reading the comments from the post most of them saying do it. Please help with getting this horrible Wesite site taken off the Internet
