The militia started firing into the crowd. Of course they're going to retaliate. Condemning them for killing one of the vigilantes is like condemning someone for shooting a guy to prevent him from killing his family...
The militias are trying to stop a fascist coup.
So you call the protestors fascists while advocating unprovoked violence against student protestors and try to justify it by claiming that the protestors are trying to undermine the state...
Seriously, how would you have responded if the NYPD indiscriminately fired into a crowd of Occupy Wall Street protestors and one of the Occupiers responded by killing a police officer? I doubt you would "condemn both sides" in that case.
