Ah. The good old 'Rules of Engagement' is rearing its ugly head again.
If a rioter is in the act of throwing a bomb, he must be warned that the troops are armed and will shoot. In Northern Ireland we were obliged to warn the bomber three times before it was deemed OK to shoot.
If he has already thrown the bomb he is no longer, in himself, a threat - so you are not entitled to shoot him. You can arrest him, and he will no doubt go through the process of law and be sent to prison with others of his kind who will all learn to be better at what they do. Then he will be released and go back to doing what he did before - only better.
But his face is well known to the soldiers on the streets so he has become a bit of a liability to his mates, who send him to the States to collect funds through NORAID which will go directly to Gaddafi to provide arms and explosives to kill and maim many more soldiers and innocent civilians. And a few years down the line he will probably claim compensation for loss of human rights, or be invited to share the future running of the country.
How much better to have put a 7.62 sleeping pill into his brain when you had the chance.
There is nothing like having to fight a war with one hand tied behind ones back, eh?
