"Most Americans would be horrified by the inhumane conditions that are common in prisons in most developing countries," said Leahy. "Prisoners, including many who have never seen a lawyer or a judge, are denied the basic necessities of life and subjected to every type of abuse by guards who act with impunity."
The Leahy-Brownback measure said prisoners at foreign detention centers are often left in "subhuman conditions," adding poor record-keeping in some countries leaves prisoners undocumented by authorities.
An identical measure was introduced by U.S. Reps. Bill Delahunt, D-Mass., and Joe Pitts, R-Pa.
"This legislation is intended to ensure that fundamental human rights abuses within prisons do not go unrecognized," said Pitts in his statement.
