One doesn't have to be "anti-cop" to be concerned when a traffic stop turns into a shooting that results in death.  

I'm all for saluting our military veterans and supporting our officers.  
However not every officer is a good one.  We all know this, that's like assuming everyone you work with is honest and a good person. 

Sadly life isn't that cookie cutter. So yes bad cops do exist.  And by bad that doesn't necessarily mean dirty as it does, negligent, dishonest, sloppy, unknowledgeable etc.  The officer who arrested the nurse for doing her job in Utah recently proved that. 

Wait for the videos to be released after they've been analyzed.  That's the best advice anyone can offer right now.
