Actually, she didn't. What she found was that different States have different standards for CCW's. If the study had further compared the incidence of gun-related crimes in the States with different standard and shown that the States with more expansive standards had greater incidence of such crimes, then she would have had something to support her ideology. But, it didn't. So she's claiming that the different standards endanger children on the basis of - no data at all, just emotional bull$#!t.
Taking a wild guess here....is this person a Democrat?
