I, too, want to see all the evidence. But, I am certainly NOT willing to make blanket statements exonerating Slager of all charges possible and pending, based upon the graphic video that has been widely disseminated.
Being familiar with shooting at targets, I am stunned by the calm and mechanical actions taken to draw down on a fleeing suspect and squeeze off 8 rounds, 5 apparently finding their mark. I did not detect one bit of apprehension in Slager's mannerisms or attitude as he set and fired and then walked upon the likely deceased Scott.
I'm beginning to look on this case as a "teaching moment", much like the Zimmerman-Martin case.
As George Zimmerman learned in his interaction with young Purple Drank Fight Club thug Trayvon, the wider world is not interested in "civilian peasants" policing their neighborhoods.
In this interaction, hopefully police in the wider world will learn that you don't need to be a "lone superhero" in this age of ubiquitous information technology. Discretion is the better part of valor, in other words.
