Your comment is a subjective one and reflects only your morality.  In the grand scheme of the universe, each and every party whose voluntary choices affect the outcome of a scenario bears responsibility for that outcome.  The choices made by the FBI agents do matter.  If they made choices and had the option to end the situation differently, then the full responsibility for the outcome rests on their shoulders as much as on Finicum's.  You cannot deny this from a logical perspective.  Cause and effect.  Make a choice and get a consequence.  The outcome was the sum of multiple choices.  To make the world better, all choices must be channeled toward productive outcomes.
