Todays news - more killings

I find it sad that today's news is focussed on more killings.
President Obama has announced that Osama bin Laden has been killed. Retribution by the west for his launching attacks on the "free world".
A NATO bomb has also supposedly killed one of Gaddafi's son and grandsons.
And in Afghanistan a 12 year old boy has launched a suicide bomb attack killing four and injuring a dozen more.
I wonder whether the world is a safer place. I doubt whether killing Osama bin Laden will change the direction of terrorist groups.
An "eye for an eye" says the bible. But does retribution work? Does the use of force make the world a safer place or is it safer for us in the west that have money, power and weapons?
Perhaps the "powers that be" (PTB's) can reflect on the need for justice and basic living conditions for all people to combat the rise in terrorism and killing of innocents. Or are none of us innocent?
I too would use force against a perceived enemy, particularly if the enemy has killed someone close to me.
