I think that's because it's all tongue in cheek enough that it's almost universally understood nobody means it when they say "noooo, don't do violence, that's bad", it's just strategic blame dodging.

And since we're already at the point where people are getting shot dead at opposition rallies, even the crazies don't feel the need to agitate further when all their ringleaders are going "shhhhh, act innocent for a minute!"
