was more interested in philosophical discussions than political ones. in the last day or two, an image pointed out by sarah palin. campaigning back in march, you'll remember palin posted a map on facebook putting cross hairs over some democratic controlled districts including giffords. at the same time palin tweeted, don't retreat. reload. representative giffords took issue with palin's imagery and here's what she said on msnbc back in march. >> we're on sarah palin's targeted list. but the thing is, the way she has it depicted has the cross hair of a gun sight over our district. will people do that? you have to realize there's consequences to that action. >> a day after that interview with representative giffords, palin was in the district campaigning with senator john mccain. here's what she said about the criticism of her weapons' metaphors. >> we know violence isn't the answer. when we take up our arms we're talking about our vote. we're talking about being involved in a contested primary like this.
