"and carefully aim it"?? How about getting to it and just firing randomly, killing just one LEO? I think that the fact that there was only one fatality in this showdown shows absolute restraint and excellent judgement on the part of  law enforcement. 
Anyone who declares that they are armed is taken seriously. The Bundy Gang waved their weapons proudly. I don't think that they were just showing off their toys. 
Is Finicum a martyr now? To whom? 
I consider him a dead Bundy lackey.
