Like Lexington, Adam Serwer puts the shooting in context: 

As with any other act of political violence, we have to be mindful of our own reactions. Political violence in the United States has never been more illegitimate. There was a time when a member of Congress could walk into the Senate and beat a political rival senseless and walk away unmolested. The South was once a place of unrestrained terrorist violence conducted with the tacit approval of local authorities. Even when those authorities were brave or responsible enough to press charges, securing guilty verdicts would be difficult because of a local culture willing to accept crimes committed in service to white supremacy. We live in a time where no major political movement would be willing to openly justify such behavior.
