The guy is being called a 'lone wolf'. Inevitably such guys are discovered to have an entire network of support on line, with friends and family giving him encouragement and religious indoctrination. The mosque he attends regularly will say they have never seen him before. His mother will say he was a good person. His father will say it is a set up by racist police to frame meek  and mild Muslims and it is all just   Islamophobia the guy has been implicated at all. 

News media, and leftist politicians  will not question any of it, accepting every word as gospel truth. The shame is Britain's for being so terrible to Muslims.
