From [HERE] A decision by state authorities in Oklahoma to keep the botched execution hidden behind a curtain from press and public observers is being legally challenged, with a leading legal rights group joining media outlets in charging that prison officials acted unconstitutionally.

The American Civil Liberties Union (ACLU) announced the lawsuit Monday in a bid to prevent the state from concealing future executions from reporters and the public.

The suit — in which the Guardian newspaper and the Oklahoma Observer also feature as plaintiffs — comes at a time of increased scrutiny over the administration of lethal injections.

Amid a growing scarcity of ingredients for the lethal drug cocktail, death penalty states are increasingly attempting to hide information pertaining to executions, including the types of drugs used and where they were brought. That secrecy, experts say, can lead to executions going horribly wrong.
