Justifying Abuse

I am not surprised that arguments like the following justifying abuse has arisen. From the NYT:
"These prisoners, they're murderers, they're terrorists, they're insurgents," he [Senator James M. Inhofe, Republican from Oklahoma] said. "Many of them probably have American blood on their hands. And here we're so concerned about the treatment of those individuals."
At the same time, the Red Cross reports that 70% to 90% of Iraqi prisoners are randomly arrested and largely innocent. Granted that abuse is not spread equally among those innocent and those heavily targetted suspects, it would still suggest that a good chunk of those abused are innocent.
