From the article:
In July, Joseph Wood gasped for air for one hour and fifty-seven minutes in Arizona during his executions with the same two-drug cocktail.
Oklahoma first used a three-drug midazolam cocktail identical to Florida's to execute Clayton Lockett last April. During his execution, an improper IV placement failed to deliver enough of the paralytic drug into his bloodstream, and he died of a massive heart attack while writhing in pain.
I imagine these are not good guys if they're on death row (and are guilty without question), but that sounds like cruel and unusual punishment. In one of the other threads on here about the Brazilian guy executed in Indonesia he was killed by firing squad. I think that's sort of a fucked up way to be executed, but I'd much rather face a firing squad instead of being killed slowly and painfully.
One hour and 57 minutes to execute Joseph Wood? That's fucked up.
