I think it might be interesting, if you are interested, to try and access todays debate in Parliament where David Cameron was in the House giving a speech and taking questions on this matter.
It is called 'The Murder Of Lee Rigby' and it was on this afternoon.
I say try and watch it as you will see what was actually said in 'context' and not by a media outlet that perhaps doesn't do it credit. There was a fair amount of cross party agreement.
Context can show a different opinion may be formed to that of the BBC or other media outlets, possibly.
