I own a car and drive it buying petrol. I am therefore aiding and abetting others who drink and drive and kill people
That's total bollox. Firstly the person who drinks and then drives is wholly responsible for drink driving. It has absolutly nothing to do with anybody else who owns a car and buys petrol. It's the person who goes into the pub/shop buys alcohol, drinks it and then drives. No one else.
People who work in shops are also breaking the law of moral codes if those same shops sell cigaretts because they kill people.
Well actually it's the manufacturers who are breaking the moral code. But because fags really do kill, it's a leagal requirment to put the health warning on the packet, and therefore passing the responsibility on to the person who smokes. Nothing to do with shop assistants.
Under the above posted laws genocide is a war-crime under English and Welsh law and therefore it's also a war-crime to assist in any way the continued commission of these crimes. The law is quite clear on this issue.
Edit
OK, there has been an investigation
Seanus you used present perfect that would sugest said investigation is finished. It's not there's an on-going investigation!
