I really doubt there will be backpedaling. In the 60's, when people got hurt, the left's reaction was denial and, when that failed, whining about good causes. There has been no fundamental change in leftist thinking since then.

It still is. Everytime theres violence involving liberals they immediately claim the perp was a govt "plant". One of the DUmmies in the DUmmie FUnnies made the claim about the guy who attacked Buchanan.
