Last Thursday, Brazil was visited by its own Columbine massacre. Wellington Menezes de Oliveira, 23, opened fire at a school in Rio de Janeiro killing 12 pupils and injuring 13 others, aged between 12 and 14 years old. Wellington killed himself minutes later, after being shot by a policeman. The country was shocked – and then the witch hunt started. It was almost inevitable that like Columbine before, video games were fingered by some looking for a simple explanation.
