‘Cheering section’ for violence: the attacks that show 4chan is still a threat

The Washington DC shooting was the most recent to spawn out of the extremist culture of unregulated chan' message boards

When police in Washington DC burst into a fifth-floor apartment building on 22 April in search of a man who allegedly had shot four people at random, they found Raymond Spencer dead by his own hand, a cache of guns and ammunition, and a poster with an ironic white supremacist meme.

The poster invoking the meme, popular on the extremist online forum 4chan, was a stark reminder that this attack blamed on Spencer, 23, was only the most recent mass casualty attack to spawn out of the ugly extremist culture of unregulated internet message boards such as 4chan.
