I wonder, since this bastard failed to murder a bunch of people, does the left

still consider it just a property crime?

First thought is 'probably'.  Because these are the same communists who considered people blocking a building's doors and then trying to burn it down, KNOWING there were people inside, to be a non-violent action.  Whereas anyone with a working brain and a non-rotted moral system knows that attempting mass murder by arson is about as violent as they could get.
