Hybrids to improve the air

“So remember if you wish to be a mass murderer there really is no need to carry around knives, guns, a dirty bomb, or even stooping as low as acid; simply become an authorised london bus driver and you can poison as many people as you can get away with for as many years as you're employed by the subs.  Just imagine 40 years of killing thousands of people and all legal to boot.  Apart from the arms, weapons or being in the military where else can you - without fear of comeback - pop off a few thousand civilians without a hitch?”
