Here is a heart wrenching story of how children are kidnapped from their beds, given a weapon and forced to join Joseph Kony’s army. In some cases they’re even made to kill their parents.
Update: It’s been brought to my attention that there is some suspicion about the way Invisible Children are behaving. I didn’t find hard evidence for the claims, but I’m linking to it so you can make your own conclusions. Metafilter also has some great discussion about the organization.
