Interesting, huh. Or rather, sinister. Either way, this is just another way that the US has trampled upon the rights of people whether though unlawful invasions based on false accusations, illegal occupation of a sovereign nation, the torture and molesting of prisoners of war and now, the encouragement of "slavery" by offering large bounties for captured "fighters". Of course, these incidents regarding the round-up of thousands of alleged fighters and sending them off to Guantanamo has been going on for a while now.
Certainly with their government's gungho attitude to fighting the "War on terrorism" the military will resort to anything to get those "terrorists".

Another example of the US military's zealousness in waging war on the terrorists at any cost is the cover-up in the death of their most famous casualty in Afghanistan, former NFL player Pat Tillman.
After releasing statements implying that Tillman was killed while heroically leading his squad in an ambush by enemy fighters, subsequent investigations revealed that Tillman was actually killed by friendly fire, essentially by his own countrymen, in a case of mistaken identity between different American army squads. However instead of telling the family right away, the military delayed and merely told the family the original and false details of his death were "incomplete".
His parents have spoken out against the military, denouncing them for their cover-up of the truth.

Excerpt of his father's remarks:
"I think they thought they could control it, and they realized that their recruiting efforts were going to go to hell in a handbasket if the truth about his death got out."
