A huge red flag for me w/regards to that abc.net article is that the author condemns the ICC's chief prosecutor for issuing an arrest warrant for Sudan's criminal, murderous leader Omar Hassan al-Bashir (see: Darfur). Incidentally, Kony and the LRA were supported by Sudan (under al-Bashir) until 2005, when an ICC warrant was issued for Kony. Birds of a feather and all that.
There's a lot to criticize about "Invisible Children" (most of the money is spent on administrative costs and "raising awareness", for example) but one of the author's major gripes about "Invisible Children" seems to be that it is an organization run by *gasp* white people that is trying to *gasp* bring a non-white person to account and colonialism *grumble grumble* colonialism.
The author also repeats the line about Kony not being a big threat since he only has a few hundred fighters. Three hundred people with guns, roaming around, constitutes a large enough force to cause trouble and kill people. If he isn't as huge a threat as he used to be, that's great, but he's still operating (see Kony resumes attacks in DRC):
The Lord’s Resistance Army rebels have resumed attacks against civilians in the Democratic Republic of Congo, leaving thousands displaced.
The new wave of attacks came after a lull of six months in DR Congo and Central African Republic where the rebels are currently operating.
At least 10 people have been abducted and 3,000 displaced in 20 attacks in Orientale Province, north-eastern DR Congo this year, said the UN refugee agency UNHCR
The overall commander of UPDF operations in Central African Republic and South Sudan, Col. Joseph Balikudembe, confirmed the attacks, saying they are occurring regularly.
