'Our soldiers shouldn't be forced to sort out what manners of interrogation are permissible by watching who is convicted of what,' said Jean Aylward, a lawyer with Human Rights First, an activist group. 'The rules need to be clear in advance and senior commanders and civilian leaders who intentionally muddy those waters must be held accountable.'"
