US security contractors funnel cash to Taleban: Senate report

Why is it that the US pays these private contractors outrageous amounts and to what end?

US funds for private security contractors in Afghanistan have flowed to warlords and Taleban insurgents, undermining the war effort and fueling corruption, according to a Senate report issued on Thursday. The investigation by the Senate Armed Services Committee found that the government had failed to vet or manage those hired to provide security under contracts worth billions of dollars, with disastrous results.

So we are aiding the enemy through these contractors with no oversight on where the money goes.

Billions disappearing and billions in contracts causing corrupt activities throughout the region.
These contractors should be indicted and their contracts pulled.

Calling it "funnelling" is a bit much.
