This bloke isn't the full shilling. (one look at his face will tell you that)
He was such a credible threat that Hate not Hope kept the info to themselves for months. Then passed it on to a HNH friendly MP who eventually passed the 'threat' on to the target.
I liked the bit about telling Hope Not Hate rather than, say, the police. I wonder whether his intention was to save a life, or to ensure there would be a decent ruck.
Definitely not carrying a full load as you say Spice.
Just deal with him, preferably in a secure unit. Not really news - just another nutter that shouldn't have been roaming the streets in the first place.
