has anyone seen the German shepherd attack a handcuffed man?

I couldn't watch much more than 10 seconds of the video without getting sick to my stomach. Videos like this make me absolutely furious at cop empathizes. He was handcuffed and not one cop or the cop with the dog could order the dog to back off. That dog should not be in K9 at all if he can't be controlled. But I guess he's just a "thug" so who cares right? Smh even the other officers there held him down so that the dog could continue attacking him!!! This makes me so angry NOTHING could have justified that! Especially when cold blooded murderers and rapists get a warm meal when they are arrested. I dare someone to tell me the bs that color doesn't matter.
