Tennessee execution fails; Christa Pike regains consciousness after pentobarbital doses

Christa Pike, a death row inmate in Tennessee, survived a botched execution attempt after receiving two doses of pentobarbital, and is now in intensive care. Her lawyers call the recovery 'unprecedented' and are seeking to preserve evidence, raising questions about the state's execution protocol and potential legal challenges. This is a rare failure of lethal injection, which may impact ongoing debates on capital punishment in the U.S.
