When tobacco companies agreed to settle 40 state lawsuits against them last June, it did so with astonishing enthusiasm considering it was going to cost them more than 368-billion dollars. Critics, who are naturally suspicious of anything the Companies find acceptable, had little to use in an argument against the settlement.....until the Minnesota tobacco trial started. When it did, momentum toward a national deal stopped and the settlement collapsed. Minnesota Public Radio's Bob Collins looks at how the Minnesota trial has changed the national debate on tobacco.
