Should cops have to wait until they are actually being gunned down before they can use force to protect themselves? What happened was an absolute tragedy, and every measure should be taken to avoid anything like that ever happening again. The shooting was not justified, and cops need better training, non-lethal options must be expanded, penalties for this kind of "prank" must be made harsher. Everyone agrees on that. But to call the cop a murderer, as if he had executed someone he knew was innocent, just for fun, that's not right either. Cops face actual murdering psychos on a daily basis, and must be able to respond to how the situation looks at the time. Again, not trying to justify the shooting, but trying to encourage a more nuanced perspective.
