Oh, so that's why he was guilty then.It's all out there. He was diagnosed as having a paranoid personality disorder and had access to guns.
Tragic case but he was an accident waiting to happen.
As mentioned above he was an active member of the BNP and wanted the country led by a far right dictator. No idea about the National Front but one of his uncles was one of the founders.
Pure coincidence but the current leader of the NF shares his name.
