Because they know it'll become more "national outrage," even if proven valid. You can even just look at the title and OP, it's designed to make you angry and believe these men were unjustified in shooting the suspects.
All I see are accurate depictions of the event
"la cops" - technically gardenia cops, but they're still police officers
"shooting 2 unarmed men" - correct
"killing one of them" - correct
The problem with reporting police behavior only in ways that make them seem evil dehumanizes them. It's detrimental to society and to the lives of those already paid poorly for putting their lives on the line. What good does "exposing" these innocent police officers do anyway? They already got processed through the legal system. What do you want?
Better non-lethal options, police officer body cameras, increased training, and (if payouts are made in settlements) cash directly from police pension funds instead of just going directly from the taxpayers to the party involved.
