We do not yet know what prompted 22-year-old accused gunman Jared Loughner to allegedly shoot Rep. Gabrielle Giffords (D-Ariz.) and others, including a child and federal judge who died from their wounds.
But critics of Sarah Palin have already drawn a link between the shooting and the fact that the former Alaska governor put Giffords on a "target list" of lawmakers Palin wanted to see unseated in the midterm elections.
In March, Palin released a map featuring 20 House Democrats that used crosshairs images to show their districts. (You can see it here.) Critics suggested at the time that she was inciting violence by using the crosshairs imagery and for later writing on Twitter to her supporters, "'Don't Retreat, Instead - RELOAD!'"
