They were all heinous and cowardly and not a subject to mock by PP who probably never came close to the carnage and aftermath of a bomb scene.
He claims he is partly death. Well so am I, I lost my hearing when in close proximity to a Post Office box containing a 'come on bomb' in Camden Hill Sq Notting Hill. Lucky the cast iron shrapnel didn't take my head off. If,as PP claims, he was a doctor then no doubt he will know of the eminent physician who was blown up whilst walking his dog. He made the mistake of prodding a package underneath his neighbour's car( a politician who was the original target)
PP would not recognise the smell of improvised explosive (ANFO or ANAL) let alone the smell after it explodes at the scene and should zip it if he considers it a matter for flippant mirth.
