Shaw, once again claiming to know better than Scotland Yard, the Met and the terrorist's own mother. Here's another expert who obviously doesn't know as much as Shaw:

Shashank Joshi, a senior research fellow at the security thinktank the Royal United Services Institute, said: "We have always known that it is exceptionally hard to understand who will become a terrorist. Masood is unusual in that only a minority become radicalised over the age of 30. His criminal record is unsurprising, as some studies show that a significant proportion of jihadists have had prior convictions."

Being an apologist for a jihadi terrorist what does that make you?
