It's possible the officer's approach to the situation/suspect contributed to causing the result. Perhaps use a whole different approach (less aggressive and more conversational), or tase the guy sooner, or back off until you have backup before continuing the encounter. The outcome might've been the same regardless, and the cop did not deserve to get shot, but cops need to realize that just issuing commands aggressively may not be the best approach and the job may require more nuance especially given the target demographic.
