... As opposed to the numerous civilians who are currently being killed by government forces without repercussion due to qualified immunity?
Though having said that, I'm not sure if qualified immunity would apply in the same way to ICE officers. If that hasn't been legally determined yet (remember - ICE didn't exist before 9/11, and legal determinations take time), and looking at how ICE is currently operating with impunity in plain clothes and unmarked vehicles... Things will get much worse than Kent State before they get better.
