You don't seek justice for a perp dumbass. You seek justice for victims. And there is only one victim in this situation.
So is being a suspect, or being Black a capital offense? When police shoot perps, there MUST be justice for that perp. Innocent until PROVEN guilty applies to each and every American citizen.
The real problem is an over militarized police force actin with impunity. When all you have is a hammer, everything looks like a nail. That's an old saying that is true. When all you have is a gun, everyone looks like a criminal. And that goes for the reactionary cops and private citizens packing heat 'for their own protection'.
