This is the type of thing that really scares me.  I would be very interested in viewing this video.  How in the world does one shoot their own relatives and two police officers? What gives this person the right to take someone else life? Those people may have had children, mothers, sisters, friends, co-workers, and now they are dead, and for what?  How did this individual go so long without being apprehended.  Sometimes the system really confuses me and upsets me.  I wish they would have caught him sooner and kept him alive so he could explain his actions.
