Sarah Palin condemns 'blood libel' over Arizona attack
Former Alaska governor Sarah Palin has attacked as a "blood libel" suggestions that political rhetoric contributed to Saturday's fatal shootings in Arizona.
Ms Palin, tipped as a possible 2012 presidential runner, hit out at "irresponsible statements" apportioning "blame for this terrible event".
"Violence isn't the answer. When we take up our arms we're talking about our vote," she said.
"Our debates are full of passion but we settle our political differences respectfully at the ballot box," she added.
